Input current to the TMCS1133-Q1 passes through the isolated high-voltage side of the package leadframe into and out of the IN+ and IN– pins. The current flowing through the package generates a magnetic field that is proportional to the input current, which is measured by an integrated on-chip galvanically-isolated, precision Hall sensor. As a result of the electrostatic shielding on the Hall sensor die, only the magnetic field generated by the input current is measured, thus limiting input voltage switching pass-through to the circuitry. This configuration allows for direct measurement of currents with high-voltage transients without signal distortion on the current-sensor output. The leadframe conductor has a low resistance and a positive temperature coefficient as defined in Electrical Characteristics.
