ZHCSQ76 December 2022 TPS25961
PRODUCTION DATA
Thermal Shutdown occurs when the junction temperature (TJ) exceeds the thermal shutdown threshold (TSD). When the TPS25961 detects thermal overload, it shut downs and remains off until it has cooled down sufficiently. Once the TPS25961 junction has cooled down below TSD - TSDHYS, it remains off for an additional delay of tTSD,RST after which it automatically retries to turn on. The device performs 3 auto-retry attempts to allow the system to recover before it latches-off if the fault persists. See Fault response section for more details on device response after a fault.
