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.
