Part Number: MCF8329A
Tool/software:
Hi there!
I have a custom PCB with a MCF8329A1IREER controller on it paired with IPB013N06NF2SATMA1 MOSFETs. Relevant control pins are connected to a micro-controller on the same PCB.
I'm trying to get basic motor operation before writing an I2C driver. I'm driving the BRAKE pin LOW (to turn off the brakes) and DRVOFF LOW (to enable the gate driver). Sending a 1kHz PWM signal to the SPEED pin results in no activity at all on a motor.
The nFAULT pin is HIGH, indicating that there is not a problem that the controller can find, yet the motor doesn't spin or make any sort of noise at all.
The driver chip also seems to get quite warm despite not doing anything, which is somewhat concerning.
Thanks for your time!
