CS5463
1. OVERVIEW
The CS5463 is a CMOS monolithic power measurement device with a computation engine and an ener-
gy-to-frequency pulse output. The CS5463 combines a programmable gain amplifier, two ?? Ana-
log-to-Digital Converters (ADCs), system calibration, and a computation engine on a single chip.
The CS5463 is designed for power measurement applications and is optimized to interface to a current
sense resistor or transformer for current measurement, and to a resistive divider or potential transformer
for voltage measurement. The current channel provides programmable gains to accommodate various in-
put levels from a multitude of sensing elements. With single +5 V supply on VA+/AGND, both of the
CS5463’s input channels can accommodate common mode plus signal levels between (AGND - 0.25 V)
and VA+.
The CS5463 also is equipped with a computation engine that calculates instantaneous power, I RMS ,
V RMS , apparent power, active (real) power, reactive power, harmonic active power, active and reactive
fundamental power, and power factor. The CS5463 additional features include line frequency, current and
voltage sag detection, zero-cross detection, positive-only accumulation mode, and three programmable
pulse output pins. To facilitate communication to a microprocessor, the CS5463 includes a simple
three-wire serial interface which is SPI? and Microwire? compatible. The CS5463 provides three out-
puts for energy registration. E1, E2, and E3 are designed to interface to a microprocessor.
