Check for Samples: LM8364 FEATURES 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. 1 2 Extremely Low Quiescent Current: 0.65ОјA, at
VIN = 2.87V
High Accuracy Threshold Voltage (В±2.5%)
Open Drain Output
Input Voltage Range: 1V to 6V
Surface Mount Package (5-Pin SOT-23)
Pin for Pin Compatible with MC33464 APPLICATIONS Low Battery Detection
Microprocessor Reset Controller
Power Fail Indicator
Battery Backup Detection 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
0.65ВµA 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 …
