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 ponents 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 parator 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 puters, intelligent instruments, controllers, critical microprocessor and microputer power monitors, portable or battery-powered equipment, automotive. - FEATURES - +3V, +3.3V, and +5V power-supply voltages - Full temperature rated - Supply current: 5µA - Available in configuration: push-pull RESET output - 140ms minimum power-on reset pulse width - Guaranteed reset to VCC = +1V - Power supply transient Immunity - Eliminating external ponents - Manual reset input - ORDERING INFORMATION Ordering Number 83CXXXG-AD4-R Note: XXX: Output Voltage, refer to Marking Information.
