• Energy Metering: U1 can measure the active, reactive, and apparent energy in a polyphase electrical system. It is capable of handling the data acquisition and processing needed for accurate energy measurement across multiple phases.
• Voltage and Current Inputs: It has separate inputs for voltage (VAP, VBP, VCP, VN) and current (IAP, IAN, IBP, IBN, ICP, ICN) for each phase, allowing it to monitor the electrical parameters in detail.
• Digital Signal Processing: U1 incorporates digital signal processing (DSP) for high accuracy in measuring energy consumption, voltage, and current. The processing capabilities also enable features like peak detection and reactive power measurement.
• Communication and Control Interfaces: With pins for Clock Input (CLKIN), Clock Output (CLKOUT), Data Input (DIN), Serial Clock (SCLK), and Data Output (DOUT), along with Chip Select (~CS) and Interrupt (~IRQ), U1 supports various communication protocols for data exchange and can interface with microcontrollers or other devices in a system.
• Power Supply and Grounding: The IC has dedicated pins for digital power supply (DVDD), analog power supply (AVDD), digital ground (DGND), and analog ground (AGND), ensuring clean and stable operation. REFIN/OUT pin is used for voltage reference for the ADC inside the IC.
