The TMAG5110-Q1 and TMAG5111-Q1 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-Q1 offers two independent digital outputs giving speed and direction calculation (TMAG5111 -Q1) or giving directly the digital output of each independent latches (TMAG5110 -Q1). This high level of integration allow the use of a single TMAG511x-Q1 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-Q1 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.
