The FAULT open-drain output is asserted (active low) during an overcurrent, overtemperature, or reverse-voltage condition. The TPS2553-Q1 device asserts the FAULT signal until the fault condition is removed and the device resumes normal operation. The TPS2553-Q1 device is designed to eliminate false FAULT reporting by using an internal delay deglitch circuit for overcurrent (7.5-ms typical) and reverse-voltage (4-ms typical) conditions without the need for external circuitry. This ensures that FAULT is not accidentally asserted due to normal operation such as starting into a heavy capacitive load. The deglitch circuitry delays the response to and release of signaling fault conditions. Overtemperature conditions are not deglitched and assert the FAULT signal immediately.
