NJW4372
Pulse Input Stepper Motor Driver
■ GENERAL DESCRIPTION
■ PACKAGE OUTLINE
The NJW4372 is a bipolar drive stepper motor driver IC
characterized as highly efficient. The control method
used is a simple pulse train input control (STEP & DIR)
method of programming. The drive stage consists of
DMOS H bridges.
Therefore, motor drive application circuit is composed of highly
effective and low heating value. Supply / interface voltage
corresponds to the logic, 3.3V / 5.0V. NJW4372 has PWM
current control circuits, Torque set, Enable and PD functions.
The functions are easy and convenient to operate and suitable
for a wide range of applications.
