Datasheet  
LED Drivers for LCD Backlights  
White LED Diver for  
Backlight of Medium/Large-sized LCDs  
BD9267KUT  
General Description  
Features  
BD9267KUT is a white LED diver used on backlight of  
Medium/Large-sized LCDs. This IC can achieve  
dimming function by SPI control. And through the SPI  
correspondence, it can set the ON/OFF of each switch,  
analog dimming and etc. The signals of PWM dimming  
can set the frequency, ON time and delay of PWM by  
inputting the external signals to the register.  
BD9267KUT has equipped several protection functions  
to deal with the abnormal states, including LED OPEN  
protection, LED SHORT protection, external current  
setting resistance SHORT protection, external MOS  
transistor SHORT protection, etc. So it can be used in a  
wide output voltage range and various load conditions.  
16-ch constant current driver (external FET(NMOSis  
equipped.)  
LED voltage can be set externally.  
PWM dimming and Analogue dimming can be  
controlled by SPI.  
LED Abnormal operation detection circuit (OPEN  
protection/ SHORT protection) is equipped.  
LED SHORT protection detection voltage is adjustable  
(LSP terminal)  
LED SHORT protection detection CH  
FAIL INDICATION function is equipped by ERR_DET  
terminal.

External FET gate driving terminal of LED constant current driver, operating range : 05V.  
ÅS1-S16  
3,6,9,12,15,18,21,24,25,28,31,34,37,40,43,46PIN)  
Connect to external FETs source terminal of LED constant current driverThrough the operations of constant current  
driver, all CHs of S1-S16 terminals are outputted the set voltages at addresses of 02h, 03h, and S1-S16 proceed the  
constant current operation.  
By monitoring the voltage of this terminal, the external resistance SHORT detection of each CH and external MOS  
SHORT during Drain-Source detection proceed.  
When DimmingHIGH, external resistance SHORT detection proceeds, and output the errors.  
When DimmingLOW, external MOS Drain-Source SHORT detection proceeds, and output the errors.  
ÅD1-D16  
2,5,8,11,14,17,20,23,26,29,32,35,38,41,44,47PIN)  
At output terminal of LED constant current driver, drain of external FET is connected. By monitoring the voltage of this  
terminal, LED OPEN detection and LED SHORT detection of each terminal proceed.  
When DimmingHIGH, if LED is in SHORT mode or OPEN mode, error signals are outputted.  
LED OPEN protection detected voltage ・・・0.1V(typ.)  
LED SHORT protection detected voltage・・・5.0V(typ.)・・・(It can be changed by setting the LSP terminal. Details are  
given in LSP Pin Description.)  
When DimmingLOW, the abnormal state when DimmingHIGH just before continues. In other words, when  
Dimming=HIGH and the abnormal state is detected, the error signal is still outputted even turned to DimmingLOW.  
To prevent the mistake of detection caused by the time change of state, abnormal detection mask can be set at address  
of 04h.

ÅLSP 50PIN)  
A pin used for setting the LED SHORT protection detecting  
voltage. When LSP pin is in OPEN state, the voltage in inward  
of IC is 1V typ.Set it in range of 0.8V~3.0V)  
When LED is lighting, if the voltage of D116 pin is higher  
than  
Voltage of LSP x 5 (V) default 5V)  
the abnormal state of IC is detected。  
Because this pin has a high impedance, please connect a  
capacitor about 1000pF to remove the noise basically.

ÅVCC  
51PIN)  
The VCC pin is used to supply power for the IC in the range of 9 to 35V. If the VCC pin voltage reaches 7.0V (Typ.) or  
more, the IC will initiate operation. If it reaches 6.7V (Typ.) or less, the IC will be shut down. Basically, insert a resistor of  
approx. 10 ohms in resistance between the VCC pin and the external power supply and install a ceramic capacitor of  
approx. 1uF in capacitance in the vicinity of the IC.  
ÅSTB  
52PIN)  
The STB pin is used to make setting of turning ON and OFF the IC and allowed for use to reset the IC from shutdown.  
Note: Set the STB pin voltage below the VCC pin voltage.  
Note: The IC state is switched (i.e., the IC is switched between ON and OFF state) according to voltages input in the STB  
pin. Avoid using the STB pin between two states (0.8 to 1.8V).  
ÅGND  
53PIN)  
The GND pin is an analog circuit ground pin of the IC. Set the ground pattern as close as possible to that of resistors  
connected to the S1 to S16 pins.  
ÅCOMP1(55PIN)  
The COMP1 pin is used to feed back the state of voltage to the external power supply in order to optimize the power  
supply voltage for the LED layer.  
Positive feedback voltage is output to a pin having the lowest voltage out of the D1 to D8 pins. If the lowest voltage of the  
D1 to D8 pins is higher than 0.6V typical voltage, the COMP1 pin will become open-circuited. If the lowest voltage of  
these pins is lower than 0.6V typical voltage, the internal NPN transistor of the COMP1 pin will turn ON. The COMP1 pin  
is intended to connect to the output voltage monitor pin of the DC/DC converter.

ÅCOMP2(54PIN)  
The COMP2 pin is used to feed back the state of voltage to the external power supply in order to optimize the power  
supply voltage for the LED layer.  
Positive feedback voltage is output to a pin having the lowest voltage out of the D9 to D16 pins. If the lowest voltage of  
the D9 to D16 pins is higher than 0.6V typical voltage, the COMP2 pin will become open-circuited. If the lowest voltage of  
these pins is lower than 0.6V typical voltage, the internal NPN transistor of the COMP2 pin will turn ON. The COMP2 pin  
is intended to connect to the output voltage monitor pin of the DC/DC converter.  
ÅCS(57PIN), CLK(58PIN,) DI(59PIN), DO(60PIN)  
These pins are used to control the IC with the CS, CLK, DI, and DO serial interfaces. Input levels are determined by the  
DVDD power supply of the digital block. For data input format and timing, refer to the description of Logic block to be  
hereinafter provided.

ÅVSYNC(61PIN), HSYNC(62PIN)  
The VSYNC and HSYNC input signals enable the PWM light modulation signal to make setting of PWM frequency, PWM  
ON time, and PWM delay time. For data input format and timing, refer to the description of Logic block to be hereinafter  
provided.  
ÅERR_DET(63PIN)  
The ERR_DET pin is used to output an IC error detection signal and provides the N-MOS open-drain output function. If  
this pin is pulled up to the DVDD voltage of the IC or else, it will be set to output High voltage for normal operation. If any  
error is detected, the internal NMOS of the IC will be put into ON state, setting the pin to output Low voltage.

LED error detection GND Level  
When the ERR_DET pin is put into the GND Level, the LED has already caused an error. In this case, reading the  
registers located at addresses 05h to 0Ch makes it possible to recognize what channel is in what type of error state. (For  
detail, refer to the description of registers to be hereinafter provided.)  
ÅDGND(56PIN)  
The DGND pin is a digital circuit ground pin of the IC. Lay out the DGND pin using interconnect independent of that for  
the GND pin wherever possible.  
ÅDVDD(64PIN)  
The DVDD pin is used to input power in the digital block of the IC in the range of 3.0 to 3.6V. When the DVDD pin voltage  
reaches 3.3V (typ.), the IC will start operating. Insert a ceramic capacitor of approx. 1uF in capacitance between the DVDD  
and DGND pins in the vicinity of the IC.

Figure 17. Setting for PWM Delay and ON Duty  
By making register setting, PWM output delay and ON duty time counts of CH1 to CH16 can be controlled.  
The above timing chart shows an example for CH1.  
(To make delay time count setting, write 06h in address 2Ch. To make ON duty time count setting, write 07h in address 0Ch.)  
The delay counter starts counting after counting three from the leading edge of VSYNC signal. When the counter reaches the  
set delay count value (06h), the duty counter will start counting simultaneously when the PWM_OUT_01 signal is set to “H”.  
Subsequently, when the duty counter reaches the set duty count value (07h), the PWM_OUT_01 signal will be set to ”L”.  
Since then, the said sequence is continuously repeated.  
The same control is also carried out for CH2 to CH16.  
The delay counter counts up to FFCh. Even if the set value exceeds this maximum value, it will also count up to FFCh.  
oft-start masking function  
A value set at address 09h serves as the pulse number of the VSYNC signal and masks the error signal control in the  
relevant section.

[Operation  
The pwm_mskcnt counter starts counting from the falling edge of HSYNC4I next to the signal that set LED_OP_01 to  
“H”. When the counter reaches the set count (02h), the err_maskcnt counter will start counting. When the counter  
reaches the set count (02h), the ERROR output signal will be set to “H”.  
Subsequently, the error state is continually monitored at the leading edge of pwm_out_01 and judged as “Error not  
detected”. After that, when the pwm_mskcnt counter reaches the set count value, the ERROR output signal will be  
set to “L”.  
The count numbers of pwm_mskcnt and err_mskcnt for the detection signal (4) are the same as those for the  
detection signals (1) to (3).

Precautions in use  
1.) This product is produced with strict quality control, but might be destroyed if used beyond its absolute maximum ratings including  
the range of applied voltage or operation temperature. Failure status such as short-circuit mode or open mode can not be  
estimated. If a special mode beyond the absolute maximum ratings is estimated, physical safety countermeasures like fuse  
needs to be provided.  
2.) The circuit functionality is guaranteed within of ambient temperature operation range as long as it is within recommended  
operating range. The standard electrical characteristic values cannot be guaranteed at other voltages in the operating ranges,  
however the variation will be small.  
3.) When this product is installed on a printed circuit board, attention needs to be paid to the orientation and position of IC. Wrong  
installation may cause damage to IC. Short circuit caused by problems like foreign particles entering between outputs or  
between an output and power GND also may cause damage.  
4.) The pin connected a connector need to connect to the resistor for electrical surge destruction.  
5.) Use in a strong magnetic field may cause malfunction.  
6.) Thermal design needs to be done with adequate margin in consideration of allowable loss (Pd) in actual operation state.  
7.) This IC includes temperature protection circuit (TSD circuit). Temperature protection circuit (TSD circuit) strictly aims blockage of  
IC from thermal runaway, not protection or assurance of IC. Therefore use assuming continuous use and operation after this  
circuit is worked needs to not be done.  
8.) This IC is a monolithic IC which has P+ isolation for separation of elements and P board between elements.  
A P-N junction is formed in this P layer and N layer of elements, composing various parasitic elements.  
For example, a resistance and transistor are connected to a terminal as shown in the figure,  
When GND>(Terminal A) in the resistance and when GND>(Terminal B) in the transistor (NPN), P-N junction operates  
as a parasitic diode.  
When GND>(Terminal B) in the transistor (NPN), parasitic NPN transistor operates in N layer of other elements nearby  
the parasitic diode described before.  
Parasitic elements are formed by the relation of potential inevitably in the structure of IC. Operation of parasitic elements can  
cause mutual interference among circuits, malfunction as well as damage. Therefore such use as will cause operation of  
parasitic elements like application of voltage on the input terminal lower than GND (P board) need to not be done.

Precaution on using ROHM Products  
1) Our Products are designed and manufactured for application in ordinary electronic equipments (such as AV equipment,  
OA equipment, telecommunication equipment, home electronic appliances, amusement equipment, etc.). If you  
intend to use our Products in devices requiring extremely high reliability (such as medical equipment, transport  
equipment, traffic equipment, aircraft/spacecraft, nuclear power controllers, fuel controllers, car equipment including car  
accessories, safety devices, etc.) and whose malfunction or failure may cause loss of human life, bodily injury or  
serious damage to property (“Specific Applications”), please consult with the ROHM sales representative in advance.  
Unless otherwise agreed in writing by ROHM in advance, ROHM shall not be in any way responsible or liable for any  
damages, expenses or losses incurred by you or third parties arising from the use of any ROHM’s Products for Specific  
Applications.  
2) ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor  
products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsibilities, adequate  
safety measures including but not limited to fail-safe design against the physical injury, damage to any property, which  
a failure or malfunction of our Products may cause. The following are examples of safety measures:  
[a] Installation of protection circuits or other protective devices to improve system safety  
[b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure  
3) Our Products are designed and manufactured for use under standard conditions and not under any special or  
extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way  
responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s Products under any
