BD9400BFP - Rohm

BD9400BFP System Power Supply

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 commun.
