I'm using the DRV8876 motor driver configured in PH/EN mode and without using PWM control input.
I am seeing an unexpected current peak at the output of the Ipropi pin each time I perform a brake (slow decay) to the motor.
Here is the capture with the oscilloscope:
The yellow corresponds to PH/EN input, the blue signal corresponds to PH/IN2 and the magenta is the Ipropi output.
The Rpropi resistor has a value of 1KOhm, therefore the relationship between the motor current and the sensed current is 1:1.
What could be the reason of having a 3A peak current when I perform a brake?
Thanks in advance
