ADE7752AARZ-RL

Overview

The ADE7752AARZ-RL is a polyphase energy metering integrated circuit manufactured by Analog Devices Inc. It operates on a single 5 V supply with a typical power consumption of 30 mW. The device supports 50 Hz and 60 Hz IEC62053-2x standards and is compatible with three-phase three-wire delta and three-phase four-wire wye configurations. It provides average real power information on low-frequency outputs F1 and F2, while the CF logic output supplies instantaneous real power for calibration. The chip features an on-chip 2.4 V reference, power supply monitoring, and creep protection.

Feature Summary

• Digital signal processing architecture ensures high accuracy over large environmental variations
• Direct drive capability for electromechanical counters and two-phase stepper motors
• Integrated no-load threshold prevents creeping under zero load conditions

Applications

• Three-phase prepayment electricity meters
• Industrial motor monitoring systems
• Auxiliary energy metering applications

Procurement Notes

Verify the specific suffix ARZ-RL against the manufacturer's current datasheet to confirm package type and reel specifications. Ensure the component matches the required IEC62053-2x compliance level for your target market. Cross-reference the manufacturing date code with project timelines to avoid obsolescence risks associated with legacy energy metering ICs.

Selection Notes

Select this component when designing three-phase metering systems requiring direct pulse outputs for mechanical registers. The ADE7752A variant is preferred over the standard ADE7752 for new designs due to its lower 30 mW power consumption. It serves as a pin-compatible replacement for the original ADE7752 in existing layouts.

Part Context

The ADE7752A is a low-power version of the ADE7752 series, officially recommended by Analog Devices for all new designs since November 2018. It maintains identical pinout and functionality to the original model while reducing typical power dissipation from 60 mW to 30 mW. The part remains in active production status as of recent industry records.

Replacement Considerations

The ADE7752A is a direct pin-compatible substitute for the ADE7752. Designers migrating from the original ADE7752 can use the ADE7752A without schematic changes to benefit from reduced power consumption.

FAQ

How does the ADE7752A differ from the standard ADE7752?

The ADE7752A offers the same pinout and functionality as the ADE7752 but features a lower typical power consumption of 30 mW compared to 60 mW.

What types of loads can the F1 and F2 outputs drive directly?

The F1 and F2 logic outputs can directly drive electromechanical counters or two-phase stepper motors.
