General Description

The NJW4372 is a high efficiency bipolar drive stepper motor driver IC, which controls steps and direction by simple input pulse train. DMOS H bridge outputs realize high efficiency, low heat motor application. The control circuit is optimized for logic power supplies and interfaces. Therefore it corresponds to plural kind of logic voltages such as 5.0V and 3.3V. The NJW4372 has PWM constant current circuits, a Torque Select function, an Enable function and a Brake function. These easy and convenient functions make NJW4372 suitable for various applications.
