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.
