■ 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.
