(1) Once the device reaches the thermal warning temperature of 160ºC, the device remains in thermal warning until the device cools to
145ºC. This is known as the thermal-warning hysteresis of the device.
(2) Once the device reaches the thermal shutdown temperature of 175ºC, the device remains in thermal shutdown until the device cools to
160ºC. This is known as the thermal-shutdown hysteresis of the device.
