Hall effect sensor for high-speed and high-temperature motor applications

The Texas Instruments DRV5015 is a low-voltage, digital-latch Hall effect sensor intended for high-speed and high-temperature motor applications. Operating from a 2.5V to 5.5V 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 provided 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 –40C to +125C.
