SLVSFZ1 December 2020 TPS27SA08-Q1
When IOUT reaches the current limit threshold, ICL, the device remains enabled and limits the current IOUT to close to the threshold, ICL . In the case that the device remains enabled and limits IOUT, the thermal shutdown and/or energy limit protection feature may be triggered due to the high amount of power dissipation in the device.
During a short circuit event, the device will hit the ICL threshold that is listed in the Specifications and then regulate the output current close to the threshold value to protect the device. The device will detect a short circuit event when the output current exceeds ICL, however the measured maximum current may exceed the ICL threshold due to the finite response time of the TPS27SA08-Q1 device current limit regulation loop. The device is guaranteed to protect itself during a short circuit event over the nominal supply voltage range (as defined in the Specifications section) at 125°C.
