8 Detailed Description

8.1 Overview

The DRV5053 device is a chopper-stabilized hall sensor with an analog output for magnetic sensing applications.

The DRV5053 device can be powered with a supply voltage between 2.5 and 38 V, and will survive –22 V

reverse battery conditions continuously. Note that the DRV5053 device will not be operating when approximately

–22 to 2.4 V is applied to VCC (with respect to GND). In addition, the device can withstand supply voltages up to

40 V for transient durations.

The output voltage is dependent on the magnetic field perpendicular to the package. The absence of a magnetic

field will result in OUT = 1 V. A magnetic field will cause the output voltage to change linearly with the magnetic

field.

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.

For devices with a negative sensitivity (that is, DRV5053RA: –40 mV/mT), a south pole will cause the output

voltage to drop below 1 V, and a north pole will cause the output to rise above 1 V.

For devices with a positive sensitivity (that is, DRV5053EA: +40 mV/mT), a south pole will cause the output

voltage to rise above 1 V, and a north pole will cause the output to drop below 1 V.
