10 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

10.1 Application Information

The key feature sets of the TMCS1100 provide significant advantages in any application where an isolated

current measurement is required.

•

Galvanic isolation provides a high isolated working voltage and excellent immunity to input voltage transients.

•

Hall based measurement simplifies system level solution without the need for a power supply on the high

voltage (HV) side.

•

An input current path through the low impedance conductor minimizes power dissipation.

•

Excellent accuracy and low temperature drift eliminate the need for multipoint calibrations without sacrificing

system performance.

•

An external reference input maximizes flexibility for unidirectional or bidirectional measurement with custom

dynamic ranges, and improves accuracy at the system level.

•

A wide operating supply range enables a single device to function across a wide range of voltage levels.

These advantages increase system-level performance while minimizing complexity for any application where

precision current measurements must be made on isolated currents. Specific examples and design requirements

are detailed in the following section.
