Micropower Undervoltage Sensing Circuits - LM8364


  • LM8365  -  プログラマブル出力遅延付き


The LM8364 series are micropower undervoltage sensing circuits that are ideal for use in battery powered microprocessor based systems, where extended battery life is a key requirement.

A range of threshold voltages from 2.0V to 4.5V are available with an active low open drain output. These devices feature a very low quiescent current of 0.65µA typical. The LM8364 series features a highly accurate voltage reference, a comparator with precise thresholds and built-in hysterisis to prevent erratic reset operation, and ensured Reset operation down to 1.0V with extremely low standby current.

These devices are available in the space saving SOT-23 5-pin surface mount package. For other undervoltage thresholds and output options, please contact Texas Instruments.


  • Extremely Low Quiescent Current: 0.65μA, at VIN = 2.87V
  • High Accuracy Threshold Voltage (±2.5%)
  • Open Drain Output
  • Input Voltage Range: 1V to 6V
  • Surface Mount Package (5-Pin SOT-23)
  • Pin for Pin Compatible with MC33464
