8.3.5 Undervoltage Lockout

An undervoltage lockout function prevents device start-up if the supply voltage on VIN is lower than approximately its threshold (see the Section 7.5 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.
