This reference design implements a single-phase energy meter using standalone multi-channel analog-to-digital converters (ADC) to sample a shunt current sensor. The combination of the shunt sensor and a ultra-low-power Hall-effect sensor (DRV5032) minimizes the effect and enables the detection of magnetic tampering attacks. The reference design achieves class 0.5S accuracy across 4000:1 input range (25mA–100A) with 8kHz 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: 2.02.00.05 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.
