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

below a preset threshold and it keep the reset signal for at least

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

In applications, the UTC 83CXXX is suitable for computers,

intelligent instruments, controllers, critical microprocessor and

microcomputer power monitors, portable or battery-powered

equipment, automotive.
