TMCS1101EVM

3

Hardware

The TMCS1101 is an isolated, current-sense op amp that provides ease-of-use and high performance.
The TMCS1101EVM is intended to provide basic functional evaluation of all TMCS1101 gain variants. The
TMCS1101EVM is not laid out for electromagnetic compatibility (EMC) testing. The TMCS1101EVM
consists of one PCB that can be snapped apart into eight individual segments; one for each of the four
gain variants in both the bidirectional (B) and unidirectional (U) configurations:

TMCS1101A1B

TMCS1101A2B

TMCS1101A3B

TMCS1101A4B

TMCS1101A1U

TMCS1101A2U

TMCS1101A3U

TMCS1101A4U

3.1

Features

The layout of the TMCS1101EVM PCB is designed to provide the following features:

Evaluation of all gain options for the TMCS1101

Ease-of-access to device pins with test points

Evaluation of high-side and low-side configurations

On-board temperature sensor

See the

TMCS1101

data sheet for comprehensive information about the TMCS1101.
