NJW4814

Dual H-Bridge Driver with Boost Converter

GENERALDESCRIPTION

■ PACKAGE OUTLINE

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.

NJW4814MLE

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.
