Description
Under Voltage Detector Series
Manufacturer

Datasheet
MC33460, MC33461
Under Voltage Detector
Series
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.
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.
