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 BOP, then the output is pulled low. If the field strength is less than BRP, then the output is released. When the applied magnetic flux density exceeds the magnetic release point (BRP) 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.
