MICRO POWER VOLTAGE DETECTOR
Pin Assignments
Description
The APX803L is brand new micro-power voltage detector series
developed by Diodes Inc. with target to be used for microprocessor
(Top View) (Top View)
(P) supervisory circuits to monitor the power supplies in P and
digital systems. It provides wide range of detection voltage level

ranging from 1.2V to 5.0V with 0.1V per step options fixed internally RESET
from circuit design. As to supply current, APX803L series requires low

These circuits perform the supervisory function by sending out a reset
SOT23/SOT323 SOT23R/SC59
signal whenever it founds the monitored V level falls below a
CC
chosen threshold voltage level and the reset signal will remain until
VCC recovers to a level higher than threshold voltage. The APX803L
has an open-drain output with an active-low output pin and features

several delay time options (0ms, 55ms, 220ms and 450ms) for
system need.
