FAULTx Response

The FAULTx open-drain outputs are asserted (active low) on an individual channel during an overcurrent or overtemperature condition. The TPS256x asserts the FAULTx signal until the fault condition is removed and the device resumes normal operation on that channel. The TPS256x is designed to eliminate false FAULTx reporting by using an internal delay "deglitch" circuit (9-ms typ) for overcurrent conditions without the need for external circuitry. This ensures that FAULTx is not accidentally asserted due to normal operation such as starting into a heavy capacitive load. The deglitch circuitry delays entering and leaving current-limited induced fault conditions. The FAULTx signal is not deglitched when the MOSFET is disabled due to an overtemperature condition but is deglitched after the device has cooled and begins to turn on. This unidrectional deglitch prevents FAULTx oscillation during an overtemperature event.
