Product Introduction

Overview

The TMCS1100A2QDRQ1 is a galvanically isolated Hall-effect current sensor produced by Texas Instruments. It is designed for high-accuracy DC or AC current measurement with excellent linearity and temperature stability. This sensor features a low-drift, temperature-compensated signal chain that ensures less than 1% full-scale error across the device temperature range. The input current flows through an internal 1.8-mΩ conductor, generating a magnetic field measured by an integrated Hall-effect sensor, which simplifies design and minimizes power loss and thermal dissipation. The device is AEC-Q100 qualified for automotive applications and operates over a wide temperature range of –40°C to 125°C.
