7.3.4 Undervoltage Lockout (UVLO)

The undervoltage lockout (UVLO) circuit monitors the input voltage (VIN) to prevent the device from turning on before VIN rises above the lockout voltage. The UVLO circuit also disables the output of the device when VIN falls below the lockout voltage. If the device includes the optional active discharge, the output is connected to ground with a 120-Ω pulldown resistor when VIN is below the lockout voltage; see the Application and Implementation section for more details.
