Features Extremely Low Quiescent Current: 0.65µA, at VIN = 2.87V High Accuracy Threshold Voltage (±2.5%) Complementary or Open Drain Output Programmable output delay by external Capacitor (100ms typ with 0.1µF) Input Voltage Range: 1V to 6V Surface Mount Package (5-Pin SOT23) Pin for pin compatible with MC33465 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 comparator 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.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
