DRV5015 (ACTIVE)

2 mT, 5.5 V hall effect latch

 

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.
