(MC33460 / MC33461) Under Voltage Detector Series

www.DataSheet4U.com MC33460, MC33461 Under Voltage Detector Series The MC33460 and MC33461 series are ultra–low power CMOS under–voltage 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 active–low 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 built–in hysteresis to prevent erratic operation and a choice of output configurations between Open Drain (MC33460) and complementary push–pull (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 ultra–miniature SC–82AB package.
