DESCRIPTION
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.
