Datasheet Summary
Dual H-Bridge Driver with Boost Converter
GENERAL DESCRIPTION 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. The dual H-bridge drivers have independent signal inputs and a fault output function, therefore the NJW4814 improves controllability from a microputer.
The input frequency of H-bridge driver is up to 300kHz.
