Japan Radio Corporation  

NJW4372

Pulse Input Stepper Motor Driver

■ GENERAL DESCRIPTION

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.
