Part Number:DRV8872-Q1
Hi,
I would like to know correct timing of nFAULT under OCP and TSD.
1. OCP
If the output current exceeds Iocp for 2 us (tOCP), the driver should turn off, but will there be delay before nFAULT goes high?
After 3ms(tRECOVERY), when it will automatically restart, is nFAULT also returned to Low?
2. TSH
Is there a delay in the output change of nFAULT as in the above case?
Is there any reference data to know the time it takes for the device to cool down after it stops at TSD?
For example, when ambient temperature is 125 ° C on the evaluation board, it took approximately how long it took to return.
In OCP, the automatic recovery is 3 ms, so I'd like to know about the approximate level, like a few usec or msec.
Best regard,
Tomoaki Yoshida
