BD7961FM  
Optical disc ICs  
Power driver IC for CD changer  
BD7961FM  
BD7961FM is a 6-channel driver IC developed for CD changer. In addition to the 4-channel BTL driver and the 2-channel  
loading driver, the 3.3V regulator and 5.0V regulator used in the peripheral circuit are also incorporated. The size  
reduction of the set is achieved by integrating functions that were used in two chips into a single chip.  
!Applications  
CD changer  
!Features  
1) This circuit is a 6-channel driver IC consisting of four BTL drivers and two loading drivers.  
2) Two wide dynamic range loading drivers of MOS output (RON=1.0).  
3) The circuit is provided with loading driver voltage setting terminals.  
4) A 5.0V regulator and a 3.3V regulator are built in.  
(Each regulator has an external PNP transistor and an ON/OFF switch)  
5) The circuit has a mute switch.  
6) A thermal shutdown circuit is built in.  
7) Since HSOP-M36 power package is used, the set requires a reduced space.

!Operation notes  
(1) BD7961FM has a built-in thermal shutdown circuit.  
When the chip temperature reaches 175°C (Typ.), the output current from all drivers is muted.  
When the chip temperature returns to 150°C (Typ.), the circuit of the driver unit starts up.  
(2) When the mute terminal (pin33) is opened or the terminal voltage is reduced to 0.5V or less, the output current of the  
BTL driver unit is muted.  
In the normal state of use, pull up the voltage to 2.0V or more.  
(3) When the voltage of the regulator switch terminals (pin8 and 9) is increased to 2.0V or more, the output from the  
regulator is muted. In the normal state of use, pull down the voltage to 0.5V or less.  
(4) When the bias terminal (pin36) voltage is reduced to 0.7V or less, the BTL driver unit is muted.  
In the normal state of use, set the voltage to 1.1V or more.  
(5) Thermal shutdown mutes all drivers. When the mute ON voltage and the bias terminal voltage are reduced, only the  
BTL drivers are muted. When the drivers are muted, the BTL driver output terminal voltage becomes the internal bias  
voltage (VCC10.7)/2V.

The output voltage can be changed by adjusting the voltage input to the LDCONT terminal (gain of 6dB Typ.).  
However, even if the input voltage is increased excessively, the output voltage will not exceed the max. output voltage that  
depends on the supply voltage.  
(7) Supply the same voltage to VCC1 (pin25), VCC2 (pin28) and VCC3 (pin26).  
Insert by the pass capacitor (approx. 0.1µF) between VCC pin and GND pin of IC as near as possible.  
(8) Connect the radiating fin with external GND.  
(9) Output pin is to avoid short-circuit with VCC, GND and other output pins.  
An integrated circuit is damaged, and smoke may come out by the case.
