3. Personal Safety
a. Wear personal protective equipment (for example, latex gloves or safety glasses with side shields)
or protect EVM in an adequate lucent plastic box with interlocks to protect from accidental touch.
Limitation for safe use:
EVMs are not to be used as all or part of a production unit.
2 Overview
The TMCS1100 Hall-effect current sense amplifier (also called an isolated current-sense amplifier) senses
magnetic flux generated from current passing through the lead frame at common-mode voltages from 0

, independent of the supply voltage. Four fixed gains are available: 50 mV/A, 100 mV/A,
200 mV/A, and 400 mV/A. These devices operate from a single 3-V to 5.5-V power supply, drawing a
maximum of 5 mA of supply current per amplifier channel. The TMCS1100 is currently available in an 8-
pin, SOIC, surface-mount package.
Table 1 lists the available gain options.
