PRODUCTION DATA.
The device implements an internal thermal shutdown to protect itself if the junction temperature exceeds 168°C. The thermal shutdown forces the device to stop switching when the junction temperature exceeds the thermal trip threshold. Once the die temperature decreases below 150°C, the device reinitiates the power-up sequence by discharging the SS pin to below 40 mV. The thermal shutdown hysteresis is 20°C.
