SHORT CIRCUIT PROTECTION
Overcurrent conditions in the TPS4000x are sensed by detecting the voltage across the main MOSFET while
it is on.
Basic Description
If the voltage exceeds a pre-set threshold, the current pulse is terminated, and a counter inside the device is
incremented. If this counter fills up, a fault condition is declared and the device disables switching for a period
of time and then attempts to restart the converter with a full soft-start cycle.
