This reference design targets measurement accuracy across the rated current range while at the same time being a cost efficient solution. This is achieved by using a highly integrated SoC device which has up to 7 channels of the 24-bit Delta-Sigma ADCs available for current measurement. For voltage measurement a 10-bit SAR ADC is used. With both current and voltage available, power measurement can now be made. This solution also has several options for communication supported such as UART, JTAG, etc. Applications include load management, sub-panels, etc.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
