4-PIN µP VOLTAGE MONITORS
WITH MANUAL RESET INPUT
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 VCC power supplies voltage dropping
below a preset threshold and it keep the reset signal for at least
140ms when VCC 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 VCC,
and the outputs are guaranteed to be in the right logic state while
VCC 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
