Preliminary
4-PIN µP VOLTAGE MONITORS
WITH MANUAL RESET INPUT
CMOS IC
„ 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.
