The TMCS1126 is a galvanically isolated Hall-effect current sensor with industry leading isolation and accuracy. An output voltage proportional to the input current is provided with excellent linearity and low drift at all sensitivity options. Precision signal conditioning circuitry with built-in drift compensation is capable of less than 1.45% maximum total error over temperature and lifetime with no system level calibration, or less than 1% maximum total error including both lifetime and temperature drift with a one-time calibration at room temperature.
AC or DC input current flows through an internal conductor generating a magnetic field measured by integrated on-chip Hall-effect sensors. Core-less construction eliminates the need for magnetic concentrators. Differential Hall sensors reject interference from stray external magnetic fields. Low conductor resistance increases measurable current ranges up to ±103A while minimizing power loss and easing thermal dissipation requirements. Insulation capable of withstanding 5000VRMS, coupled with minimum 8.1 mm creepage and clearance provide up to 1100VDC reliable lifetime reinforced working voltage. Integrated shielding enables excellent common-mode rejection and transient immunity.
Fixed sensitivity allows the device to operate from a single 3V to 5.5V power supply, eliminating ratiometry errors and improving supply noise rejection. TI provides the TMCS1126xxB as a lower-cost option.
