Manufacturer Part Number
njw4371
Description
Dual H Bridge Driver
Manufacturer
New Japan Radio Co.,Ltd
Datasheet
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.
