Part Number: DRV8701

Hi,

In attached DRV8701 TI PSPICE output waveform with all default settings ,18V 6mA profile Vgh2 is expected to be 0V but it is High for some time.

    Hi Pritesh,

    Your inquiry is under review. 

    Please allow until Monday for a response.

    Hi Pritesh,

    Can you tell me what the inputs are in the "default" mode? 

    Are you in PWM mode and sending PWM signals to both inputs (IN1 & IN2) or PH/EN mode?

    From the waveforms it looks like you are switching between FWD and BRAKE (slow decay) which is a normal operation. However, I am not sure of the spike on GH2. I have tested on an evaluation module in the lab, and could not reproduce the behavior in PH/EN mode switching from FWD to BRAKE (slow decay). 

    Best,

    David
