GENERAL DESCRIPTION

The ADE7752B1 is an accurate active energy measurement IC intended for use in any 3-phase distribution system and has enhanced features that make it better suited for 3-phase 3-wire applications compared to the ADE7752/52A.

FEATURES

High accuracy supports 50 Hz/60 Hz IEC62053-21

Less than 0.1 error over a dynamic range of 500 to 1

Compatible with 3-phase 3-wire delta and 3-phase 4-wire Wye configurations

Supplies average active power on the frequency outputs F1 and F2

High frequency output (CF) is intended for calibration and supplies instantaneous active power

Logic output REVP indicates a potential miswiring or negative power on the sum of all phases

Direct drive for electromechanical counters and 2-phase stepper motors (F1 and F2)

Proprietary ADCs and DSP provide high accuracy over large variations in environmental conditions and time

On-chip power supply monitoring

On-chip creep protection (no load threshold) based on the sum of the three phases

On-chip reference 2.4 V ± 8 (25 ppm/°C typical) with external overdrive capability

Single 5 V supply, low power (TBD mW typical)

Low cost CMOS process
