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.
