5. Thermal shutdown
When the chip temperature increases to 160°C (Typ.), the thermal shut down circuit works and the power switch is turned
OFF. When the chip temperature falls to 140°C (Typ.), the power switch output returns (to normal). This operation will
repeat itself until the causes of the chip temperature rise are removed or until the power switch output is turned off.
The thermal shutdown circuit is in operation when the power switch is ON (when EN signal is active).
