General Description
The NJW4382 is a high efficiency bipolar drive stepper motor driver IC, which controls steps and direction by "Phase & I0/I1"input. Stepping resolution is available with "Full", "Half", "Modified half" and "Quarter" by using combination of I0 and I1. 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 NJW4382 is suitable for various stepper motors.
