1 Overview
The TMAG5110 and TMAG5111 are 2-dimensional, dual digital-latch Hall effect sensors designed for high-speed
and high-temperature motor applications. The devices are optimized for applications leveraging rotating ring
magnets. Using the alternating magnetic flux density of the ring magnet, each device presents independent
digital outputs based on the state of each of the onboard Hall effect latches to enable external or internal speed
and direction decoding. Alternating north and south magnetic poles are required to toggle the output of each Hall
effect latch, and integrated hysteresis provides robust switching.
The TMAG5110/1 are available in two sensitivity options, with B
OPmax
and B
RPmin
thresholds of ±1.4 mT and ±3
mT. Each sensitivity option is available with axes of sensitivity of XY, ZX, or ZY. These devices operate from
a single 2.5-V to 38-V power supply, drawing a typical operating supply current of 6 mA across the operating
temperature and power supply voltage ranges. These devices are currently available in a 5-pin SOT-23 package.
This EVM uses a 5-V supply and both the TMAG5110B2 and TMAG5111B2, with sensitivity in the ZX axes and a
maximum threshold of ±1.4 mT.
Table 1-1 lists the axes of sensitivity and thresholds for each device.
