NJW4371 DUAL H BRIDGE DRIVER GENERAL DESCRIPTION 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 can individually 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.
