微功耗欠压检测电路 MICROPOWER UNDERVOLTAGE SENSING CIRCUITS

Micropower Undervoltage Sensing Circuits

The MC33464 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. These devices feature a very low quiescent bias current of 0.8 µA typical.

MC33464 Features:

•Extremely Low Standby Current of 0.8 µA at Vin= 1.5 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

•Two Surface Mount Packages SOT–89 or SOT–23 5–Pin
