PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
Input current to the TMCS1107 passes through the isolated side of the package leadframe through the IN+ and IN– pins. The current flow through the package generates a magnetic field that is proportional to the input current, and measured by a galvanically isolated, precision, Hall sensor IC. 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 nominal resistance of 1.8 mΩ at 25°C, and has a typical positive temperature coefficient as defined in Electrical Characteristics.
