Automotive, high-sensitivity, 2D, dual-channel, speed and direction outputs, Hall-effect latch

The TMAG5110-Q1 and TMAG5111-Q1 are 2-dimensional, dual Hall-effect latches operating from a 2.5V to 38V 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 allows the use of a single TMAG511x-Q1 device instead of two separate latches.

The device is offered in a standard 3mT operating point, as well as a high-sensitivity 1.4mT 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.
