9.4.4 Thermal Shutdown

The TPS25750 features a central thermal shutdown as well as independent thermal sensors for each internal

power path. The central thermal shutdown monitors the overall temperature of the die and disables all functions

except for supervisory circuitry when die temperature goes above a rising temperature of T SD_MAIN. The

temperature shutdown has a hysteresis of TSDH_MAIN and when the temperature falls back below this value, the

device resumes normal operation.

The power path thermal shutdown monitors the temperature of each internal PP5V-to-VBUS power path and

disables both power paths and the VCONN power path when either exceeds TSD_PP5V. Once the temperature

falls by at least TSDH_PP5V, the path can be configured to resume operation or remain disabled until re-enabled

by firmware.
