Hot-selling and scarce ADE7858ACPZ Polyphase Multifunction Energy Metering IC QFN40 spot stock

Product Features

Highly accurate; supports EN 50470-1, EN 50470-3,

IEC 62053-21, IEC 62053-22, and IEC 62053-23 standards

Compatible with 3-phase, 3- or 4-wire (delta or wye), and

other 3-phase services

Supplies total (fundamental and harmonic) active, reactive

(ADE7878, ADE7868, and ADE7858 only), and apparent

energy, and fundamental active/reactive energy (ADE7878

only) on each phase and on the overall system

Less than 0.1% error in active and reactive energy over a

dynamic range of 1000 to 1 atTA = 25°C

Less than 0.2% error in active and reactive energy over a

dynamic range of 3000 to 1 atTA = 25°C

Supports current transformer and di/dt current sensors

Dedicated ADC channel for neutral current input (ADE7868 and

ADE7878 only)

Less than 0.1% error in voltage and current rms over a

dynamic range of 1000 to 1 atTA = 25°C

Supplies sampled waveform data on all three phases and on

neutral current

Selectable no load threshold levels for total and

fundamental active and reactive powers, as well as for

apparent powers

Low power battery mode monitors phase currents for

antitampering detection (ADE7868 and ADE7878 only)

Battery supply input for missing neutral operation

Phase angle measurements in both current and voltage

channels with a typical 0.3° error

Wide-supply voltage operation: 2.4 V to 3.7 V

Reference: 1.2 V (drift +5 ppm/°C typical) with external

overdrive capability

Single 3.3 V supply

40-lead lead frame chip scale package (LFCSP), Pb-free

Operating temperature: −40°C to +85°C

Flexible I2C, SPI, and HSDC serial interfaces
