Product details

1.65 V omnipolar Hall switch — low-voltage detection for battery and portable gear

The BU52077GWZ-E2: The BU52077GWZ- is a CMOS-output omnipolar Hall effect switch that responds to both north and south pole magnetic fields, with a typical operating supply down to 1.65 V. Magnetic thresholds are ±19 mT for the operate point and ±10.1 mT for the release point, tested at 25°C — wide enough hysteresis to reject noise in lid-close or position-detect applications. Output sink current is rated 0.5 mA maximum, sufficient to drive a logic-level input or a small LED indicator directly.

Active lifecycle — no PCN or EOL on record

Sourced through authorized distribution channels; tape/reel (TR) and cut-tape (CT) packaging options available.
