BL-HE-ST8514 Bipolar Hall Effect Switch

BL-HE-ST8514

The bipolar Hall sensor element consists of a Hall plate, a circuit board and a magnet. When a magnet acts on the Hall piece, the carrier in the Hall piece is affected by the Lorentz force and moves in a specific direction inside the Hall piece, thus generating a certain potential difference on both sides of the Hall piece, and the circuit board will The voltage signal at both ends of the Er chip is amplified and processed into a standard signal to output a readable magnetic field strength value. Since bipolar Hall sensors require positive and negative polarity power supplies, the wiring positions of "+" and "-" polarity are usually marked on the interface.

01、This Bipolar Hall effect switch is monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150°, and is more stable with both temperature and supply voltage changes. The negative compensation slope is optimized to match the negative temperature coefficient of low cost magnets.

02、Band gap regulation provides extremely stable operation over 3.8 to 30 VDC supply voltage range. BL-HE-ST8514 Hall Switch is capable of continuous 40 mA sinking output, and may be cycled as high as 60 mA maximum

(At 4.5v to 24V with 20mA load unless otherwise noted.)
