Overview
NJW4814
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 microcomputer.
The input frequency of H-bridge driver is up to 300kHz.
