8.4 Device Functional Modes

8.4.1 Operation with VDD < 4.25 V (minimum VDD)

The devices operate with VDD voltages above 4.75 V. The maximum UVLO voltage is 4.75 V, and operates at

VDD voltages above 4.75 V. The typical UVLO voltage is 4.5 V. The minimum UVLO voltage is 4.25 V. At VDD

below the actual UVLO voltage, the devices do not operate, and OUT remains low.

8.4.2 Operation with IN Pin Open

If the IN pin is disconnected (open), a 100 k

Ω internal resistor connects IN to GND to prevent unpredictable

operation due to a floating IN pin, and OUT remains low.

8.4.3 Operation with ILIM Pin Open

If the ILIM pin is disconnected (open), the current limit threshold is set at 0.5 V.

8.4.4 Operation with ILIM Pin High

If the signal on ILIM pin is higher than 1 V, the current limit threshold is clamped at 1 V.
