This reference design implements a single-phase with neutral or split-phase energy measurement subsystem using one isolated and one non-isolated standalone multichannel analog-to-digital converters (ADCs) with two shunts. The combination of shunt sensors and a low-power linear 3D Hall-effect sensor, TMAG5273, provides both protection and enables the detection of magnetic tampering attacks. The reference design achieves class 0.2 S accuracy across 4000:1 input range (25mA to 100A) with 4kHz sampling rate and uses a TI Arm® Cortex®-M0+ host microcontroller for calculating the metrology parameters. The necessary software functionality is implemented in MSPM0-SDK Version: 2.01.00.03 and can be compiled with TI Code Composer Studio™.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
