Datasheet Summary
Micro-Stepping Motor
Driver
Introduction NCV70501 is a micro- stepping 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.
