NJW4813
Dual Half Bridge Driver with Boost Converter
GENERAL DESCRIPTION
The NJW4813 is a dual half bridge driver with boost converter IC.
Output voltage boost from Li-ion battery and a 5V power supply and
can drive a piezo device by two half bridge drivers.
The NJW4813 is able to stable startup by soft start function in boost
SW.REG..
The dual half bridge driver improves control characteristics from a
microcomputer in response to independent signal input in each channel.
The input frequency operates to 300kHz and in the case of failure, it
can output a fault flag.
