7.3.4 Thermal Shutdown

The device has two internal overtemperature shutdown thresholds, T_{TH_OTSD1} and T_{TH_OTSD2}, to protect the internal FET from damage and overall safety of the system. When the device temperature exceeds T_{TH_OTSD1}, any switch in current limit (OUT switch or VCONN switch) is disabled. The device does auto-retry recovery by re-enabling the switch when die temperature decreases by 20°C. When T_{TH_OTSD2} is exceeded all open drain outputs are left open and the device is disabled such that minimum power/heat is dissipated. The device does auto-retry recovery by attempting to power-up when die temperature decreases by 20°C.
