I have look through the DRV8834 and family, and will like to know if there's any method to know (feedback to mcu) whenever an ITRIP condition occurs.
It seems to me that the SENSE resistors + amp is in place to detect a voltage > VREF to signal an ITRIP condition and stop the Hbridge, but there don't seem to be an output to signal that ITRIP occurs.
If there's no such functionality built in, I am thinking of sampling the Rsense with an external amplifer to tell the MCU about the ITRIP condition. Do you think that will work? When an ITRIP event occurs, does the ITRIP actually stop current flowing through the Rsense resistors?
