PRODUCTION DATA.
The junction temperature (Tj) of the device is monitored by an internal temperature sensor. When Tj exceeds the thermal shutdown temperature, the device goes into thermal shutdown. The power stage is turned off and PG goes low. When Tj decreases below the hysteresis amount, the converter resumes normal operation, beginning with a Soft Start cycle. To avoid unstable conditions, a hysteresis of typically 20°C is implemented on the thermal shutdown temperature. In addition, the thermal shutdown is debounced by approximately 10 µs.
