The ADE7752B supplies average active power information on the low frequency outputs, F1 and F2. These logic outputs can be used to directly drive an electromechanical counter or to interface with a microcontroller (MCU). The CF logic output gives instantaneous active power information. This output is intended to be used for calibration purposes.
The ADE7752B includes a power supply monitoring circuit on the VDD pin. The ADE7752B remains inactive until the supply voltage on VDD reaches 4 V. If the supply falls below 4 V, the ADE7752B resets and no pulses are issued on F1, F2, and CF.
Internal phase matching circuitry ensures that the voltage and current channels are phase matched. An internal no load threshold ensures that the ADE7752B does not exhibit any creep when there is no load.
The ADE7752B is available in a 24-lead SOIC package.
