7 Summary

This document examined several facets of device operation and specification related to the TMCS110x device sensitivity, and discussed several options for best practices in layout and design. However, other factors not related to the sensitivity of the device should also be taken into consideration, such as common-mode rejection ratio (CMRR), power supply rejection ratio (PSRR), and offset.

In addition to these practices, take thermal considerations into consideration when designing with the TMCS11xx product family. Additional information on thermal design is discussed in Thermal Implementation Guide for In-Package Magnetic Current Sensors application note.
