(1) After the device reaches the thermal warning temperature of 160°C, the device will remain in thermal warning until the device cools to 145°C. This is known as the device's thermal warning hysteresis.
(2) After the device reaches the thermal shutdown temperature of 175°C, the device will remain in thermal shutdown until the device cools to 160°C. This is known as the device's thermal shutdown hysteresis.
