DESCRIPTION

· The TMCS1101 is a galvanically isolated Hall-effect current sensor for DC or AC current measurement, offering high accuracy, excellent linearity, and temperature stability.
· It features a low-drift, temperature-compensated signal chain with less than 1.5% full-scale error across the temperature range.
· The device includes an internal 1.8-mΩ conductor for current flow, generating a magnetic field measured by an integrated Hall-effect sensor, eliminating the need for external concentrators.
· It provides 600-V lifetime working voltage and 3-kV RMS basic isolation, with integrated electrical shielding for common-mode rejection and transient immunity.
· Available in unidirectional and bidirectional sensing variants, it operates from a single 3-V to 5.5-V power supply, with fixed sensitivity options to eliminate ratiometry errors and improve supply noise rejection.
