the mc33460 and MC33461 series are ultralow power cmos undervoltage detectors with very tight threshold accuracy specifically designed for accurate monitoring of power supplies. the devices are optimized for use in battery powered systems where low quiescent current and small packaging are required. the device generates an activelow signal whenever the input voltage falls below the factory set 2% threshold. hysteresis is provided to ensure reliable output switching. the mc33460/1 series features a highly accurate voltage reference, a comparator with a precision voltage threshold, and builtin hysteresis to prevent erratic operation and a choice of output configurations between open drain (mc33460) and complementary pushpull (MC33461). the products are offered in 9 standard voltage thresholds ranging from 0.9v to 4.5v. other threshold voltages from 1.0 to 5.0v are available in 100mv steps. the devices can operate to a very low input voltage level and are housed in the ultraminiature sc82ab package. features ? available in open drain or pushpull output ? output state guaranteed to v in = 0.8 v ? tight detector voltage accuracy ( 2.0%) ? extended temperature operation (40 c to 85 c) ? ultra low quiescent current (0.8 m a at v in = 1.5 v typical) ? wide range of operating voltage (0.7 v to 10 v) applications ? low battery detector ? powerfail indicator ? microprocessor reset generator ? window comparator ? battery backup circuit representative block diagrams mc33460 nch open drain configuration MC33461 cmos configuration v ref v in out gnd v ref v in out gnd sc82ab sq suffix case 419c http://onsemi.com see detailed ordering and shipping information in the package dimensions section on page 2 of this data sheet. ordering information pin connections 4 1 14 3 2 (top view) v in out gnd n/c
