MD30C - sinking PWM control?
Posted: Thu Oct 01, 2015 9:37 am
Hello - I am interested in using the MD30c as a fuel pump controller for a car. The engine control unit can output a PWM signal, but it is a negative signal. Is this compatible with the MD30C if I hook up the PWM to the ground (Input Pin 1 on the header that takes the PWM input) and feed the "PWM" pin (Input Pin 2 on the same header) a constant 5V?
Also - is it necessary to feed a signal to the DIR pin? If not, what direction is the default?
Thanks.
