PIN NAME

FUNCTION DESCRIPTION

1

VDD

Bias IC from nominal 2.7V to 4V

2

PGOOD

PGOOD is the boolean AND function of all the UV inputs being satisfied. This is an open drain output and

can be pulled high to the appropriate level with an external resistor. Additionally a 20k

 pull up to VDD is

provided internally.

3

ENABLE

Enabling input for supervisory function. Has a 10µA pull-up to VDD

4

GND

IC ground

5-8

VMON1

VMON2

VMON3

VMON4

These inputs provide for a programmable monitored voltage threshold referenced to an internal 0.63V

reference. These inputs have a 30µs glitch filter to prevent transient upsets from being recognized by

PGOOD.
