MC33461SQ-20CTR Datasheet

Under Voltage Detector Series


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.

•Available in Open Drain or Push–Pull Output
•Output State Guaranteed to Vin= 0.8 V
•Tight Detector Voltage Accuracy (±2.0%)
•Extended Temperature Operation (–40°C to 85°C)
•Ultra Low Quiescent Current (0.8 µA at Vin = 1.5 V typical)
•Wide Range of Operating Voltage (0.7 V to 10 V)

•Low Battery Detector
•Power–Fail Indicator
•Microprocessor Reset Generator
•Window Comparator
•Battery Backup Circuit
