Short Circuit Protection Response
Figs 13-14 show over current protection reaction time of the IRAUDAMP8 in a short circuit event.
As soon as the IRS2093 detects an over current condition, it shuts down PWM. After one second,
the IRS2093 tries to resume the PWM. If the short circuit persists, the IRS2093 repeats try and fail
sequences until the short circuit is removed.
