Thermal protection
In order to avoid damage due to high junction temperature, a thermal shutdown protection is
implemented. When the junction temperature rises above 150 °C (typ.), the device turns off
both the control logic and the boost converter and holds the FAULT pin low. The LDO is kept
alive and normal operation is automatically resumed after the junction temperature has
been reduced by 30 °C.
