PRODUCTION DATA.
The device incorporates a TSD circuit as a protection from overheating. For continuous normal operation, the junction temperature should not exceed the TSD trip point. If the junction temperature exceeds the TSD trip point, the output is turned off. When the junction temperature decreases by 15°C (typical) than the TSD trip point, the output is turned on again. The SENSE voltage is internally pulled up to a voltage rail between 2.7 V and 3 V during TSD status.
NOTE
The purpose of the design of the internal protection circuitry of the TPS7B770x-Q1 family of devices is to protect against overload conditions and is not intended as a replacement for proper heat-sinking. Continuously running the device into thermal shutdown degrades device reliability.
