83CXXX_11 Overview

4-PIN μP VOLTAGE MONITORS WITH MANUAL RESET INPUT

UNISONIC TECHNOLOGIES CO., LTD
83CXXX
Preliminary
CMOS IC
4-PIN µP VOLTAGE MONITORS
WITH MANUAL RESET INPUT
DESCRIPTION
The UTC
83CXXX
is a microprocessor supervisory circuit. It has
an active-low RESET and push-pull outputs. The circuit can assert
a reset signal as long as the V
CC
power supplies voltage dropping
below a preset threshold and it keep the reset signal for at least
140ms when V
CC
has risen above the reset threshold. The reset
threshold can be operated with multi-supply voltages.
The UTC
83CXXX
provides the circuit with perfect reliability and
low cost through eliminating external components and adjustments
when applied with +5V, +3.3V, +3.0V power supply The UTC
83CXXX
also provide a de-bounced manual reset input.
The reset comparator can work despite of fast transients on
V
CC
, and the outputs are guaranteed to be in the right logic state
while V
CC
is down to 1V.
In applications, the UTC
83CXXX
is suitable for computers,
intelligent instruments, controllers, critical microprocessor and
microcomputer power monitors, portable or battery-powered
equipment, automotive.
FEATURES
* +3V, +3.3V, and +5V power-supply voltages
* Full temperature rated
* Supply current: 5µA
* Available in configuration: push-pull RESET output
* 140ms minimum power-on reset pulse width
* Guaranteed reset to V
CC
= +1V
* Power supply transient Immunity
* Eliminating external components
* Manual reset input
