Undervoltage Lockout
An undervoltage lockout function prevents device start-up if the supply voltage on VIN is lower than
approximately its threshold (see the Electrical Characteristics table). When in operation, the device automatically
enters the shutdown mode if the voltage on VIN drops below the undervoltage lockout threshold. The device
automatically restarts if the input voltage recovers to the minimum operating input voltage.
Overtemperature Protection
The device has a built-in temperature sensor which monitors the internal IC temperature. If the temperature
exceeds the programmed threshold (see the Electrical Characteristics table) the device stops operating. As soon
as the IC temperature has decreased below the programmed threshold, it starts operating again. There is a
built-in hysteresis to avoid unstable operation at IC temperatures at the overtemperature threshold.
