TMCS1101EVM

This user’s guide describes the characteristics, operation, and use of the TMCS1101 evaluation module
(EVM). This EVM is designed to evaluate the performance of the

TMCS1101

voltage output isolated Hall-

effect current sense amplifiers in a variety of configurations. Throughout this document, the terms
evaluation board, evaluation module, and EVM are synonymous with the TMCS1101EVM. This document
includes a schematic, reference printed-circuit board (PCB) layouts, and a complete bill of materials
(BOM).
