Micropower Undervoltage Sensing Circuits with Programmable Output Delay

The MC33465 series are micropower undervoltage sensing circuits that are specifically designed for use with battery powered microprocessor based systems, where extended battery life is required. A choice of several threshold voltages from 0.9 V to 4.5 V are available. This device features a very low quiescent bias current of 1.0 µA typical.

Features:

•Extremely Low Standby Current of 1.0 µA at Vin= 3.5 V

•Wide Input Voltage Range (0.7 V to 10 V)

•Monitors Power Supply Voltages from 1.1 V to 5.0 V

•High Accuracy Detector Threshold (±2.5)

•Two ResetOutput Types (Open Drain or Complementary Drive)

•Programmable Output Delay by External Capacitor (100 ms typ. with 0.15 µF)

•Surface Mount Package (SOT–23 5–Pin)

•Convenient Tape and Reel (3000 per Reel)
