Hi,
I am using DRV8432DKDEVM evaluation board with parallel mode (i.e. MODE 3 M3 - 0, M2-1, M1-0)and have interfaced (GND, PWM 01, PWM 02) TMS320F28335 development board for providing PWM pulses.
The issue i am facing is whenever i switch on the PVDD signal (i.e 15Volt or 48 volt) input PWM signal gets distorted. and same when i off the PVDD supply it comes back.
NO error ( over current , over temp etc ) is occurred during this period. the signals at FAULT and OTW are constantly HIGH state.
Hardware wise i have connected the PWM signal from controller to board using wires.
Let me know if we can connect an external controller to generate PWM signal to this board?
