PRODUCTION DATA
An internal temperature sensor monitors the junction temperature (TJ) of the device. If TJ exceeds 160°C (typ.), the device goes into thermal shutdown. Both the high-side and low-side power FETs turn off and PG goes into the high-impedance state. When TJ decreases below the hysteresis level, the converter resumes normal operation, beginning with soft start. To avoid unstable conditions, the device implements a hysteresis of typically 20°C on the thermal shutdown temperature.
