3 Description

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.
