°C

(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.
