HICCUP mode during an OCP

Thermal shutdown

When the junction temperature reaches 150°C ±10°C the device enters in thermal shutdown.

Both MOSFETs are turned off and the soft-start capacitor is rapidly discharged with an internal

switch. The device doesn't restart until the junction temperature goes down to 120°C and, in

any case, until the voltage at the soft-start pin reaches 500mV.
