UNISONIC TECHNOLOGIES CO.
, LTD 83CXXX Preliminary 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 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 provi...
