7.1 Overview
The DRV5023 device is a chopper-stabilized Hall sensor with a digital output for magnetic sensing applications. The DRV5023 device can be powered with a supply voltage between 2.5 and 38 V, and will survive –22 V reverse-battery conditions. The DRV5023 device does not operate when –22 to 2.4 V is applied to the VCC pin (with respect to GND pin). In addition, the device can withstand supply voltages up to 40 V for transient durations.
The field polarity is defined as follows: a south pole near the marked side of the package is a positive magnetic field. A north pole near the marked side of the package is a negative magnetic field.
The output state is dependent on the magnetic field perpendicular to the package. A strong south pole near the marked side of the package causes the output to pull low (operate point, BOP), and a weak south pole causes the output to release (release point, BRP). Hysteresis is included in between the operate point and the release point therefore magnetic-field noise does not accidentally trip the output.
An external pullup resistor is required on the OUT pin. The OUT pin can be pulled up to VCC, or to a different voltage supply. This allows for easier interfacing with controller circuits.
