The undervoltage lockout circuit causes the output to go Hi-Z if the selected power supply does not exceed the IN1/IN2 UVLO, or if
neither of the supplies exceeds the internal VDD UVLO.

TTL- and CMOS-compatible input pins. Each pin has a 1-mA pull-up. The Truth Table
illustrates the functionality of D0 and D1.

above the UVLO threshold and at least one supply exceeds the internal VDD UVLO.
A resistor (RILIM) from ILIM to GND sets the current limit IL to 250/RILIM and 500/RILIM for the

Power switch output
In the auto-switching mode (D0 = 1, D1 = 0), an internal power FET connects OUT to IN1 if
VSNS

I
the VSNS voltage is greater than 0.8 V. Otherwise, the FET connects OUT to the higher of
IN1 and IN2. The Truth Table illustrates the functionality of VSNS.
