CS5464
Three-channel, Single-phase Power/Energy IC
Features & Description
? Energy Linearity: ±0.1% of Reading over
1000:1 Dynamic Range
? On-chip Functions:
- Voltage and Current Measurement
Description
The CS5464 is a watt-hour meter on a chip. It
measures line voltage and current and calcu-
lates active, reactive, apparent power, energy,
power factor, and RMS voltage and current.

Active, Reactive, and Apparent Power/Energy
RMS Voltage and Current Calculations
Current Fault and Voltage Sag Detection
Calibration
Phase Compensation
Temperature Sensor
There are two separate inputs to measure line,
ground, and/or neutral current enabling the me-
ter to detect tampering and to continue
operating. An internal RMS voltage reference
can be used if voltage measurement is disabled
by tampering.

Power Supply Configurations
GND: 0 V, VA+: +5 V, VD+: +3.3 V to +5 V
Four ?? analog-to-digital converters are used to
measure voltage, two currents, and temperature.
The CS5464 is designed to interface to a variety
of voltage and current sensors.
Additional features include system-level calibra-
tion, voltage sag and current fault detection,
peak detection, phase compensation, and ener-
gy pulse outputs.
