7.1 Overview

The DRV5015 is a magnetic sensor with a digital output that latches the most recent pole measured. During power-up, in the absence of an external magnetic field, the DRV5015A1 and DRV5015A2 default to a low output state and the DRV5015A3 defaults to a high output state. Applying a south magnetic pole near the top of the package causes the DRV5015A1 and DRV5015A2 output to drive low, whereas a north magnetic pole causes this output to drive high. Applying a south magnetic pole near the top of the package causes the DRV5015A3 output to drive high, whereas a north magnetic pole causes this output to drive low. The absence of a magnetic field causes the output to continue to drive the current state, whether low or high.

The device integrates a Hall effect element, analog signal conditioning, offset cancellation circuits, amplifiers, and comparators. These features provide stable performance across a wide temperature range and resistance to mechanical stress.
