3 Description

The DRV5015-Q1 is a low-voltage digital-latch Hall

effect sensor designed for high-speed and hightemperature

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 +150°C.
