AEC-Q100 automotive omnipolar Hall switch
The DRV5033AJQDBZTQ1: It responds to both north and south magnetic poles with a symmetrical ±12 mT typical operate point and ±1 mT release point, making it suitable for position and proximity sensing in brushed DC motors, seat adjusters, and door-latch actuators where the magnet polarity is not fixed.
Supply, output, and temperature-grade fit
Runs from a 2.5 V supply rail with a typical supply current of 2.7 µA — the low quiescent draw suits always-on sensing in battery-backed automotive modules where every microamp matters. The open-drain output sinks up to 30 mA and requires a pull-up resistor to the logic supply; the output is active-low when the magnetic field exceeds the operate threshold, and it returns high-impedance at the release point.
