FUNCTION DESCRIPTION
Bias IC from nominal 2.7V to 5V
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 20kΩ pull up to VDD is
provided internally.
Enabling input for supervisory function. Has a 10µA pull-up to VDD
IC ground
These inputs provide for a programmable monitored voltage threshold referenced to an internal 0.633V
reference with 1% accuracy. These inputs have a 30µs glitch filter to prevent transient upsets from being
recognized by PGOOD.
