ADE7762 is a polyphase energy metering IC with phase drop indication. It supports high accuracy metering at 50Hz/60Hz with less than 0.1% error over a dynamic range of 500:1. The IC is compatible with 3-phase, 3-wire delta and 3-phase, 4-wire Wye configurations and provides average active power outputs and high frequency outputs for calibration. It also features phase sequence error detection, dropout indication for each phase, and on-chip power supply monitoring.
The ADE7762 is a high‑accuracy polyphase energy‑metering IC that meets IEC‑62053‑21 requirements. It uses on‑chip ADCs and DSP to perform all signal processing digitally, providing superior stability over temperature and time. The device supplies average active‑power information on low‑frequency outputs F1 and F2 and instantaneous power on a high‑frequency CF output for calibration.
The datasheet includes a functional block diagram, pin‑out table, timing diagrams, absolute‑maximum ratings, and detailed specifications such as supply voltage, reference voltage, accuracy, and input characteristics. It also describes the multiplexed LED_CTRL output used for phase‑drop, sequence‑error, and reverse‑power indication, and provides typical connection diagrams and an ordering guide.
