万彩网100线路HK401F is a high-voltage bipolar Hall switch chip made using a specialized high-voltage bipolar manufacturing process. This chip integrates a voltage regulator unit, Hall voltage generator, differential amplifier circuit, temperature compensation circuit, and open collector output circuit. It works by sensing magnetic flux density and generating corresponding digital voltage signals. HK401F is renowned for its high voltage surge resistance and strong noise resistance, making it suitable for various applications such as electronic consumption, automotive, and industrial control. Provide TO92S direct insertion packaging, SMT SOT23-3L packaging, and environmentally friendly packaging that complies with ROHS standards.

The high-voltage resistant bipolar Hall switch chip includes a voltage modulation circuit, Hall chip, signal amplification circuit, and Schmitt trigger circuit. The voltage modulation circuit provides a reference voltage for the Hall sensor, which senses a magnetic field perpendicular to the sensor surface to generate a Hall voltage, amplifies it, and sends it to the Schmitt trigger. At the same time, the chip also integrates a reverse power protection diode to protect the chip from reverse voltage breakdown.
