1 Overview
The TMAG5115 is a family of high-performance, wide input voltage, low-output delay and low-jitter Hall-effect
latch sensors. Designed for system challenges where higher magnetic precision is needed, each device variant
exhibits a different magnetic sensitivity. If the field strength is greater than B
OP
, then the output is pulled low.
If the field strength is less than B
RP
, then the output is released. When the applied magnetic flux density
exceeds the magnetic release point (B
RP
) threshold, the device output returns to a high voltage state. The
TMAG5115EVM comes prepopulated with TMAG5115B1 variant for out of the box evaluation. Other variants can
be sampled from
www.ti.com . Table 1-1 lists the different device variants in the TMAG5115 family. TMAG5115
devices can operate with a VCC range of 2.5 V to 26 V and is available in a standard SOT-23 package.
