Product Introduction

Overview

The TMCS1101A3UQDRQ1 is a galvanically isolated Hall-effect current sensor produced by Texas Instruments. This device is designed for high accuracy DC or AC current measurement, offering excellent linearity and temperature stability. It features a low-drift, temperature-compensated signal chain that ensures a total error of less than 1.5% across the device temperature range of –40°C to 85°C. The sensor integrates an internal 1.8-mΩ conductor, which generates a magnetic field measured by an integrated Hall-effect sensor, eliminating the need for external concentrators and minimizing power loss and thermal dissipation.

The TMCS1101A3UQDRQ1 provides inherent galvanic insulation with a 600-V lifetime working voltage and 3-kVRMS basic isolation between the current path and circuitry. It also includes integrated electrical shielding for excellent common-mode rejection and transient immunity.
