ADE7752AARZ

Product Summary

The ADE7752AARZ is a Polyphase Energy Metering IC with Pulse Output. The ADE7752AARZ supplies average real power information on the low frequency outputs, F1 and F2. These logic outputs may be used to directly drive an electromechanical counter or to interface with an MCU. The ADE7752AARZ remains inactive until the supply voltage on VDD reaches 4 V. If the supply falls below 4 V, no pulses are issued on F1, F2, and CF.
