3 Description

The DRV5015 is a low-voltage digital-latch Hall effect

sensor designed for high-speed and high-temperature

motor applications. Operating from a 2.5-V to 5.5-V

power supply, the device senses magnetic flux

density and presents a digital output based on

predefined magnetic thresholds.

Alternating north and south magnetic poles are

required to toggle the output and integrated

hysteresis provides robust switching.

The device is offered in two magnetic threshold

options and an inverted output option. The high

magnetic sensitivity provides flexibility in low-cost

magnet selection and component placement.

The device performs consistently across a wide

ambient temperature range of –40°C to +125°C.
