Summary of TEXAS INSTRUMENTS TMAG511X 2-DIMENSIONAL DUAL HALL-EFFECT LATCHES
Texas Instruments TMAG511x are dual 2D Hall-effect latches for rotating-magnet motor applications, operating from 2.5V to 38V and –40°C to +125°C. They integrate two sensors and signal chains to provide either independent digital outputs (TMAG5110) or speed and direction outputs (TMAG5111). Offered in ±1.4mT and ±3mT sensitivities and three axis combinations (X-Y, Z-X, Z-Y), they feature 40 kHz bandwidth, open-drain outputs, and protection including reverse-supply, 40V survival, short-circuit protection, and output current limitation.
Parts used in the TMAG511x Project:
- Texas Instruments TMAG5110 2-Dimensional Dual Hall-Effect Latch (independent 2D outputs)
- Texas Instruments TMAG5111 2-Dimensional Dual Hall-Effect Latch (speed and direction outputs)
- TMAG511xx2 variant (±1.4 mT sensitivity)
- TMAG511xx4 variant (±3 mT sensitivity)
- Planar Hall sensor axis combinations: X-Y
- Planar Hall sensor axis combinations: Z-X
- Planar Hall sensor axis combinations: Z-Y
- Power supply supporting 2.5V to 38V operation
- Rotating magnet for motor applications
Texas Instruments TMAG511x 2-Dimensional Dual Hall-Effect Latches operate 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 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 allows the use of a single TMAG511x 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 Texas Instruments 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.
