AH401F Datasheet | Vinbelltech

Features - Operates from 3.8 V to 60 V supply voltage - Overvoltage protection capability up to 80 V - Highest ESD performance up to ±4 k V - Short-circuit protected open-drain output - Wide temperature range from -40 °C to 150 °C - Reverse-voltage protection at VSUP pin - Ideal sensor for applications in extreme automotive and industrial environments - Tiny SOT23 (-SU) package and TO92 (-UA )package 3. Potential Applications - Brushless DC motor mutation - Speed measurement - Revolution counting - Angular position detection - Proximity detection 4. Block Diagram The circuit includes temperature pensated voltage regular, Hall plate, signal amplifier and Schmitt-Trigger in single silicon chip. The regulated voltage provides the reference voltage for the hall plate. A magnetic field perpendicular to the sensor surface generates a hall voltage, which is amplified and then sent to a Schmitt trigger. A protection diode against reverse power supply is integrated.
