PRODUCTION DATA
The VIN pin voltage supplies the internal control circuits of the device and provides the input voltage to the power stage. The input voltage for VIN can range from 4 V to 18 V. The device implements internal UVLO circuitry on the VIN pin. The device is disabled when the VIN pin voltage falls below the internal VIN UVLO threshold. The internal VIN UVLO threshold for start-up is 3.95 V typically with hysteresis of 150 mV.
A second means to enable the device is provided by interfacing to the EN pin. See Section 7.3.3 for more details.
