Overview
EVMs are not to be used as all or part of a production unit.
2 Overview
The
TMCS1123
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 V
to ±1100 V
, independent of the supply voltage. The device is available with zero-input reference point
DC
configurations of 0.5 × V
S
50 mV/A, 75 mV/A, 100 mV/A, and 150 mV/A. These devices operate from a single 3-V to 5.5-V power supply,
drawing a maximum of 9.2 mA of supply current. The
lead, surface-mount package.
