NCV70514 Description
The NCV70514 is a micro−stepping stepper motor driver for bipolar QFN32, 5x5 CASE 488AM N70514−x FAWLYYWW G stepper motors. The chip is connected through I/O pins and an SPI interface with an external microcontroller. The NCV70514 contains a current−translation table and takes the next micro−step depending on 1 32 the clock signal on the “NXT” input pin and the status of the “DIR” (= direction) register or input pin.
