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 TSD_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.
