  • NCV70501 is a microstepping stepper motor driver for bipolar stepper motors. The chip is connected through I/O pins and an SPI interface with an external microcontroller.
    The NCV70501 contains a current-translation table and takes the next micro-step depending on the clock signal on the NXT input pin and the status of the DIR (direction) register or input pin.
    The chip provides an error message if stall, an electrical error or an elevated junction temperature is detected. It is using a proprietary PWM algorithm for reliable current control.
    NCV70501 is fully compatible with the automotive voltage requirements and is ideally suited for general-purpose low current range stepper motor applications in the automotive, industrial, medical, and marine environment.
