Closed Loop Integrated Fluxgate-Based Current Measurement Reference Design with Bit Stream Output (TIDA-00907)

The TIDA-00907 reference design provides a reference solution for accurately measuring three phase inverter currents using Closed-loop Fluxgate magnetic current sensors. It consists of magnetic core with compensation winding interfaced to driver IC with built-in Fluxgate sensor. The design provides bit-stream output using non-isolated delta-sigma modulators with an option to connect to 3.3V or 5V microcontrollers for Digital Filtering. Use of delta-sigma modulators enable customized filtering for control algorithm and over-current protection of power switches.
