NJW4813 - Dual Half Bridge Driver

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..

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. ■ PACKAGE OUTLINE NJW4813SE3 FEATURES Boost Converter Block Output Switch Voltage Switching Current PWM Control Operating Voltage Range Oscillation Frequency Range Soft Start Function Over Current Protection http://www.
