The MC33981 fully operates down to DC. To reset a latched Fault the INHS pin must go low for the "Time to reset Fault Diagnosis"
(tRSTDIAG).
Values for CBOOT=100 nF. Refer to the paragraph entitled
production tested.
Turn-ON delay time measured from rising edge of INHS that turns the output ON to V
Turn-OFF delay time measured from falling edge of INHS that turns the output OFF to V
