Xinyide Technology SDI7768 Single-Phase Multifunction Anti-Theft Metering Chip Datasheet

The SDI7768 chip provides comprehensive metering functions for single‑phase anti‑theft applications. It measures active power, reactive power, and various energy quantities while delivering two independent power‑measurement channels and RMS voltage measurement. The device supports full‑digital gain, phase and offset calibration and offers both SPI and RSIO serial interfaces for communication with external MCUs.

Key features include a typical power consumption of 32 mW, an internal 2.5 V±3 % reference, SSOP‑24 package, and built‑in power‑monitoring circuitry that resets the chip when AVDD falls below 4 V and enables normal operation above 4.3 V. The datasheet details pin assignments, electrical limits, and typical application circuits for anti‑theft metering. This manual is written in Chinese.
