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 provide a de-bounced manual reset input.
