PRODUCTION DATA.
An undervoltage lockout function prevents device start-up if the supply voltage on VINA is lower than approximately its threshold (see Electrical Characteristics). When in operation, the device automatically enters the shutdown mode if the voltage at VINA drops below the undervoltage lockout threshold. The device automatically restarts if the input voltage recovers to the minimum operating input voltage.
