NJW4371
DUAL H BRIDGE DRIVER
• GENERAL DESCRIPTION
• PACKAGE OUTLINE
The NJW4371 is a general purpose dual H Bridge driver IC. It
consists of a pair of Nch DMOS H bridges, gate driving charge
pump circuit, thermal shut down and UVLO circuit. Each H
bridge canindividually be controlled with TTL/CMOS compatible
signal. Therefore, it is applicable for a wide range of applications
such as driving a two phase stepping motor, two DC brushless
motors, solenoids, lamps and other high voltage switching needs
using micro controller.
