TECHNICAL NOTE  
System Power Supply LSIs for use in automotive electronics  
System Power Supply IC  
with Connunication Function  
(Master Type)  
BD9400BFP  
Description  
The BD9400BFP can be combined with the BD9401FM/BD9403FV to create application-specific system power supplies.  
It can be controlled using an I2C BUS. The BD9400BFP is a main control chip featuring an I2C BUS bidirectional  
communications function, a VDD LDO (for microcontroller use), a VDD reset, and BD9401FM/BD9403FV control circuits. The  
IC's I2C BUS communications function allows switching regulator and high-side switch on/off control, as well as switching  
regulator frequency adjustment, using a maximum of 3 channels. The I2C BUS read function can be used to send power  
supply overvoltage and undervoltage detection signals, as well as switching regulator output short detection signals.  
Features  
1) The IC can be combined with the BD9401FM/BD9403FV to provide design flexibility.  
2) On/off control of up to 6 outputs with I2C BUS control  
3) Broad input voltage range: 7 V to 36 V  
4) Built-in LDO regulator for use with microcontrollers  
5) LDO regulator: 3.3 V, 250 mA (±2% precision)  
6) Built-in regulator voltage detection reset circuit  
7) Built-in power supply overvoltage and undervoltage detection circuits  
8) Dual reference voltage sources for BD9401FM/BD9403FV (VREF, VREG), and built-in triangular waveform oscillator  
9) VREF reference voltage precision: ±1%  
10) The triangular waveform oscillator frequency can be changed to ±10% or ±20% using I2C BUS control.  
11) Flag output for undervoltage detection, overvoltage detection, and BD9401FM/BD9403FV short protection detection  
signals  
12) Total system stand-by current of 60 µA (Typ.) when VDDLDO, reset, overvoltage, and undervoltage detection circuits  
are set.  
13) Package: HSOP25  
Applications  
Car audio, satellite navigation systems, etc.
