The LM8364 series is a micropower undervoltage detection circuit ideal for battery-powered microprocessor-based systems where extending battery life is a critical requirement.
A threshold voltage range from 2.0V to 4.5V 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 relatively accurate threshold, and a built-in hysteresis to prevent unstable reset operation with a very low standby current drop to 1.0V, and to guarantee reset operation.
These devices are available in a space-saving SOT23 5-pin surface mount package. For other undervoltage thresholds and output options, please contact National Semiconductor.
