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 ∆Σ 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

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.
