ADE7752B:  3-Phase, 3-Wire, and 4-Wire Energy Metering IC with Pulse Output

Product Description

The ADE7752B* is a high accuracy polyphase electrical energy measurement IC. The ADE7752B specifications surpass the accuracy requirements as quoted in the IEC62053-21 standard. The only analog circuitry used in the ADE7752B is in the analog-to-digital converters (ADCs) and reference circuit. All other signal processing (for example, multiplication, filtering, and summation) is carried out in the digital domain. This approach provides superior stability and accuracy over extremes in environmental conditions and over time.

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.
