LM8365 Micropower Undervoltage Sensing Circuits with Programmable Output Delay March 2003 LM8365 Micropower Undervoltage Sensing Circuits with Programmable Output Delay General Description The LM8365 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 or CMOS, output. These devices feature a very low quiescent current of 0.65µA typical. The LM8365 series Features a highly accurate voltage reference, a parator with precise thresholds and built-in hysterisis to prevent erratic reset operation, a time delayed output which can be programmed by the system designer, and guaranteed Reset operation down to 1.0V with extremely low standby current. These devices are available in the space saving 5-Pin SOT23 surface mount package. For additional undervoltage thresholds and output options, please contact National Semiconductor.
