3 Description

The TMAG5110-Q1 and TMAG5111-Q1 are

2-dimensional, dual Hall-effect latches operating from

a 2.5V to 38V power supply. Designed for highspeed

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.
