ZHCSJQ2A May 2019 – August 2019 TPS2596
PRODUCTION DATA.
Thermal Shutdown will occur when the junction temperature (TJ) exceeds the thermal shutdown threshold (TSD). When the TPS2596x0 variant detects thermal overload, it will be shut down and remain latched off until the device is power cycled or re-enabled by toggling the EN/UVLO pin. When the TPS2596x1 variant detects thermal overload, it will remain off until it has cooled down sufficiently. Once the TPS2596x1 junction has cooled down below TSD - TSDHYS, it will remain off for an additional delay of tTSD,RST after which it will automatically retry to turn on if it is still enabled.
Device | Enter TSD | Exit TSD |
---|---|---|
TPS2596x0 (Latch-Off) | TJ ≥ TSD | TJ < TSD - TSDHYS and Power Cycle (VIN < VUVP(F)) / Enable Cycle (VEN < VSD) |
TPS2596x1 (Auto-Retry) | TJ ≥ TSD | TJ < TSD - TSDHYS and tTSD-RST timer expired |
