General Description
The NJW4382A is a high efficiency bipolar drive stepper motor driver IC with constant current control circuit. It can operate "Full Step", "Half Step" and Brake by "2 Logic Inputs Control". It has characteristics such as low quiescent current, high output current, 40V tolerance and low ON resistance output. Internal protection circuits are Under Voltage Lockout (UVLO), Thermal Shutdown (TSD) and Over Current Protection (OCP). Therefore, the NJW4382A is suitable for various stepper motors.
