7.1 Overview
The DRV5013 device is a chopper-stabilized Hall sensor with a digital latched output for magnetic sensing
applications. The DRV5013 device can be powered with a supply voltage between 2.5 and 38 V, and
continuously survives continuous –22-V reverse-battery conditions. The DRV5013 device does not operate when
–22 to 2.4 V is applied to the V_CC pin (with respect to the GND pin). In addition, the device can withstand
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 south pole near the marked
side of the package causes the output to pull low (operate point, B_OP), and a north pole near the marked side of
the package causes the output to release (release point, B_RP). 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 V_CC, or to a different
voltage supply. This allows for easier interfacing with controller circuits.
