ADE7752B is a 3-phase, 3-wire, and 4-wire energy metering IC with pulse output. It features high accuracy, supports 50Hz/60Hz frequency, and is compatible with various configurations. It provides average active power and instantaneous active power outputs. The IC also has reverse wiring and negative power detection, and is suitable for driving electromechanical counters and 2-phase stepper motors.
The ADE7752B is a high‑accuracy polyphase energy‑metering integrated circuit that supports 3‑phase, 3‑wire delta and 3‑phase, 4‑wire wye configurations. It supplies average active power on low‑frequency outputs (F1, F2) and a high‑frequency calibration output (CF), and includes on‑chip reference, power‑supply monitoring, and creep protection.
Key features include a single 5 V supply, less than 0.1 % measurement error over a wide dynamic range, logic outputs for direct drive of electromechanical counters or stepper motors, and extensive pin‑level specifications for analog and digital interfaces.
