The TPS25990 relies on the proper component connections and biasing on the IMON, ILIM and IREF pins along with the appropriate threshold digital configurations to provide overcurrent and short-circuit protection under all circumstances. As an added safety measure, the device uses the following mechanisms to ensure that the device provides some form of overcurrent protection even if any of these pins are not connected correctly in the system or the associated components have a failure in the field or if the configuration registers are not programmed correctly.
