Description
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.
Features
- Precise current measurement through 7 channels of Delta-Sigma ADCs
- < 1% from 10% to 100% of rated current (controlled by CT & burden resistor)
- Voltage measurement enabled with integrated SAR ADC
- Extended temperature range operability of -40°C to +105°C
- Integrated single chip solution results in a cost and area efficient solution
- Large MSP Family & Roadmap / Scale performance, features, price
- Metering library available in source for use on MSPs
- Low cost, easy to use development tools and reference designs / Fast time-to-market
