General 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.

Key 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 tr.
