Overview: NJW4814 Dual H-Bridge Driver with Boost Converter GENERAL.

Datasheet Details

The NJW4814 is a dual H-bridge driver with boost converter IC.

It can boost the output voltage from Li-ion battery and/or a 5V power supply and drives a piezo device by two H- bridge drivers.

48ms of internal fixed soft start function of the boost circuit sets a limit to startup current.
