TMCS1101/TMCS110-Q1 Isolated Current Sensors

Texas Instruments TMCS1101/TMCS1101-Q1 Precision Isolated Current Sensors are galvanically isolated Hall-effect current sensors capable of DC or AC current measurement with high accuracy, excellent linearity, and temperature stability. A low-drift, temperature-compensated signal chain provides <1.5% full-scale error across the device temperature range. The input current flows through an internal 1.8mΩ conductor that generates a magnetic field measured by an integrated Hall-effect sensor. This structure eliminates external concentrators and simplifies design. Low conductor resistance minimizes power loss and thermal dissipation. Inherent galvanic insulation provides a 600V lifetime working voltage and 3kVRMS basic isolation between the current path and circuitry. Integrated electrical shielding in the Texas Instruments TMCS1101 enables excellent common-mode rejection and transient immunity.
