TPS1HC100-Q1: Thermal Behavior

Hello Kura, 

Above that screenshot there are good explanations of thermal behavior for Relative Thermal Shutdown, Absolute Thermal Shutdown, and Latch-off mode. For TREL in state 1 it says "When the power FET temperature rises TREL amount above the controller junction temperature ΔT = TFET – TCON > TREL, the device shuts down." This isn't just when the device hits 60C. This process is assuming the device is enabled into an overcurrent event and the FLT pin is low. 

For Absolute Thermal Shutdown after it reaches 165C the device does not recover until both TJ < TABS – Thys and the tRETRY timer has expired.
