NCV70516
Micro-stepping Motor Driver
Description
The NCV70516 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 NCV70516 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 an electrical error, an under−voltage or an elevated junction
temperature is detected. It is using a proprietary PWM algorithm
for reliable current control.
