An undervoltage lockout ensures that the power switch is in the OFF state at power up. Whenever the input voltage falls below approximately 2 V, the power switch will be quickly turned OFF. This facilitates the design of hot-insertion systems where it is not possible to turn OFF the power switch before input power is removed. The UVLO will also keep the switch from being turned ON until the power supply has reached at least 2 V, even if the switch is enabled. Upon reinsertion, the power switch will be turned ON, with a controlled rise time to reduce EMI and voltage overshoots.
