Features

• High Linearity Energy Computation: Realizes exceptionally tight energy data linearity within plus/minus 0.1 percent of reading over a wide 1000:1 dynamic range.

• On-Chip Parameter Calculations: Instantly measures and computes real energy, instantaneous power, root-mean-square current (I-RMS), and root-mean-square voltage (V-RMS).

• Smart Auto-Boot Functionality: Supports an autonomous boot mode from an external serial EEPROM, enabling full field operation without an independent host microcontroller.

• Integrated Peripheral Drivers: Features an on-chip energy-to-pulse conversion output capable of directly driving external mechanical counters or stepper motor indicators.

• Shunt Sensor Optimization: Current input channel interface is tailored to accurately process low-voltage signals generated from low-cost shunt resistors.

• Low Operational Power Draw: Minimizes system thermal footprints with a highly efficient typical active power consumption of less than 12 mW.

• Onboard System Supervision: Incorporates a dedicated hardware watchdog timer and an integrated power supply voltage monitor to ensure structural processing reliability.

Applications

• Electronic Residential Power Meters: Serves as the high-accuracy computing core for single-phase utility billing hardware.

• Smart Power Strips and Outlets: Implements localized real-time load diagnostics and power consumption data tracking.

• Industrial Sub-Metering Equipment: Tracks plant machinery energy footprints to optimize phase balancing and operational overhead.

• Inverters and Power Conditioners: Monitors line voltage tracking parameters and input-to-output current transfer metrics.
