When Thermal Shutdown Circuit Operates

While the thermal shutdown circuit is activated, the output pins are in the OFF status. However, the IC does not

enter the standby status even if all the CLT pins are deasserted inactive at the same time.

The thermal shutdown circuit is not activated even if the junction temperature exceeds 150

°C TYP. while the IC is

in the standby mode (when all the CTL pins are inactive).
