The TMCS1101-Q1 is a galvanically isolated Hall-effect current sensor 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 1.8-mΩ 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 600-V lifetime working voltage and 3-kV_RMS basic isolation between the current path and circuitry. Integrated electrical shielding enables excellent common-mode rejection and transient immunity.

The output voltage is proportional to the input current with four sensitivity options. Fixed sensitivity allows the TMCS1101-Q1 to operate from a single 3-V to 5.5-V power supply, eliminates ratiometry errors, and improves supply noise rejection. The current polarity is considered positive when flowing into the positive input pin. Both unidirectional and bidirectional sensing variants are available.

The TMCS1101-Q1 draws a maximum supply current of 6 mA, and all sensitivity options are specified over the operating temperature range of –40°C to +125°C.
