THERMAL SHUTDOWN
The device implements an internal thermal shutdown to protect itself if the junction temperature exceeds 170°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 155°C, the device reinitiates the power-up sequence
by discharging the SS pin to 0 volts. The thermal shutdown hysteresis is 15°C.
