3 Description

The TMCS1123 is a galvanically isolated Hall-effect

current sensor with industry leading isolation and

accuracy. An output voltage proportional to the

input current is provided with excellent linearity and

low drift at all sensitivity options. Precision signal

conditioning circuitry with built-in drift compensation

is capable of less than 1.75 maximum total error

over temperature and lifetime with no system level

calibration, or less than 1 maximum total error with

a one-time room temperature calibration (including

both lifetime and temperature drift).

AC or DC input current flows through an internal

conductor generating a magnetic field measured

by integrated on-chip Hall-effect sensors. Coreless

construction eliminates the need for magnetic

concentrators. Differential Hall sensors reject

interference from stray external magnetic fields. Low

conductor resistance increases measurable current

ranges up to ± 96A while minimizing power loss and

easing thermal dissipation requirements. Insulation

capable of withstanding 5000VRMS, coupled with

minimum 8.1 mm creepage and clearance provide

up to 1100VDC reliable lifetime reinforced working

voltage. Integrated shielding enables excellent

common-mode rejection and transient immunity.

Fixed sensitivity allows the TMCS1123 to operate

from a single 3V to 5.5V power supply, eliminates

ratiometry errors, and improves supply noise

rejection.
