The TMAG5110 and TMAG5111 are 2-dimensional, dual Hall-effect latches operating from a 2.5 V to 38 V power supply. Designed for high-speed and high-temperature motor applications, these devices are optimized for applications leveraging rotating magnets. Integrating two sensors and two separate signal chains the TMAG511x offers two independent digital outputs giving speed and direction calculation (TMAG5111) or giving directly the digital output of each independent latches (TMAG5110). This high level of integration allow the use of a single TMAG511x device instead of two separate latches.

The device is offered in a standard 3 mT operating point, as well as a high-sensitivity 1.4 mT operating point. The higher magnetic sensitivity provides flexibility in low-cost magnet selection and mechanical component placement. The TMAG511x is also available in three 2-axis combination options (X-Y, Z-X, Z-Y) to allow flexible placement of the sensor relative to the magnet.

The device performs consistently across a wide ambient temperature range of –40 °C to +125 °C.
