Voltage Detector IC Series  
Bipolar  
Voltage Detector IC  
BD47□□G series  
No.10006EBT05  
Description  
The BD47□□G Series is a reset IC that was developed to prevent system errors at transient state when the power of CPU  
or logic circuit switches ON/OFF or momentary shut down. These ICs consist of three terminals (power supply, GND and  
reset output) to detect power supply voltages and outputs reset signals of various systems. These ICs are ultra-compact  
and are realized low current consumption, making them ideal for portable products.  
Features  
1) Detection voltage range: 0.1-volt step line-up 1.9~4.6V (Typ.)  
2) High accuracy voltage detection: ±1%  
3) Low current consumption  
4) Open collector “L” reset output  
5) Compact SSOP5 package  
Applications  
All electronic devices that use microcontrollers and logic circuits

Technical Note  
BD47□□G series  
Explanation of Operation  
BD47□□G series has the detection voltages and release voltages as threshold voltages and, as the voltages applied to the  
input reach their respective threshold voltages, the output switches from “High” to “Low” and from “Low” to “High”. The  
release voltage has a hysteresis that is the detection voltage +50mV (Typ.), preventing chattering in the output. When the  
input is greater than the release voltage, the output is in a “High” state. When the input is lowered from that state, the output  
switches to “Low” on the detection voltage. When the input is less than the detection voltage, the output is in a “Low” state.  
When the input is raised from that state, the output switches to “High” with the release voltage. Additionally, at least 0.85V is  
required for the circuit to operate fully. When the input falls below the operating limit voltage, the output becomes unsettled.

When the power supply is turned on, the output is unsettled from after over the operating limit voltage (VOPL) until  
TPHL. There fore it is possible that the reset signal is not outputted when the rise time of VDD is faster than TPHL.  
2
When VDD is greater than VOPL but less than the reset release voltage (VS + ΔVS), the output voltages will switch to  
Low.  
3
If VDD exceeds the reset release voltage (VS + ΔVS), then VOUT switches from L to H.  
4
If VDD drops below the detection voltage (VS) when the power supply is powered down or when there is a power  
supply fluctuation, VOUT switches to L (with a delay of TPHL).  
5
The potential difference between the detection voltage and the release voltage is known as the hysteresis width (ΔVS).  
The system is designed such that the output does not flip-flop with power supply fluctuations within this hysteresis width,  
preventing malfunctions due to noise.  
<Precautions>  
Please be aware that when there is resistance on the power supply line, the detection voltage varies with voltage drops  
caused by the IC current consumption.  
Please connect a capacitor between VCC and GND when the power supply line has high impedance.

BD47□□G series  
Circuit Applications  
1) The following is an example of an application circuit using Reset IC for normal power supply detection. BD47□□G  
series requires a pull up resistor on the output terminal. The pull up resister value should be decided. As the  
application with enough confirmation of power supply level and output current capability. When a capacitor has been  
inserted into the output terminal to delay the output time or to remove noise, the output will be slower during starting or  
stopping. Please be careful to select the appropriate pull up resistors, output current and capacitor when inserting a  
bypass capacitor between input and GND. Please be aware that if an extremely large capacitor is used, the response  
time will become excessively slow.

2) The following shows an example of adding delay time to a reset signal. It is possible to set the delay time using the  
capacitor CL and the resistor RL connected to the output terminal as shown below. At VCC start up, CL will be  
charged by RL. The CL and RL time constants and the threshold voltage of the Reset terminal determine the charge  
delay time. When VCC is decreased, CL is discharged through the Reset IC. The sum of the respective times plus the  
delay time of the IC itself becomes the reset signal delay time.

Technical Note  
BD47□□G series  
Operation Notes  
1. Absolute maximum range  
Absolute Maximum Ratings are those values beyond which the life of a device may be destroyed. We cannot be defined the  
failure mode, such as short mode or open mode. Therefore a physical security countermeasure, like fuse, is to be given  
when a specific mode to be beyond absolute maximum ratings is considered.  
2. GND potential  
GND terminal should be a lowest voltage potential every state. Please make sure all pins, which are over ground even if,  
include transient feature.  
3. Electromagnetic Field  
Mal-function may happen when the device is used in the strong electromagnetic field.  
4. Bypass Capacitor for Noise Rejection  
Please put into the capacitor between VCC pin and GND, to reject noise. If extremely big capacitor is used, transient  
response might be late. Please confirm sufficiently for the point.  
5. Short Circuit between Terminal and Soldering  
Don’t short-circuit between Output pin and VCC pin, Output pin and GND pin, or VCC pin and GND pin. When soldering the  
IC on circuit board, please be unusually cautious about the orientation and the position of the IC. When the orientation is  
mistaken the IC may be destroyed.  
6. This IC has extremely high impedance terminals. Small leak current due to the uncleanness of PCB surface might cause  
unexpected operations. Application values in these conditions should be selected carefully. If the leakage is assumed  
between the VOUT terminal and the GND terminal, the pull-up resistor should be less than 1/10 of the assumed leak  
resistance.  
7. External parameters  
The recommended parameter range for RL is 2k~1M. There are many factors (board layout, etc) that can affect  
characteristics. Please verify and confirm using practical applications.  
8. Power on reset operation  
Please note that the power on reset output varies with the VDD rise up time. Please verify the actual operation.  
9. Precautions for board inspection  
Connecting low-impedance capacitors to run inspections with the board may produce stress on the IC. Therefore, be  
certain to use proper discharge procedure before each process of the test operation.  
To prevent electrostatic accumulation and discharge in the assembly process, thoroughly ground yourself and any  
equipment that could sustain ESD damage, and continue observing ESD-prevention procedures in all handing, transfer  
and storage operations. Before attempting to connect components to the test setup, make certain that the power supply is  
OFF. Likewise, be sure the power supply is OFF before removing any component connected to the test setup.  
10. When the power supply, is turned on because of in certain cases, momentary Rash-current flow into the IC at the logic  
unsettled, the couple capacitance, GND pattern of width and leading line must be considered.
