Description
The CS5466 is a low-cost power meter solution incorpo-
rating dual delta-sigma (
Σ) analog-to-digital converters
(ADCs), an energy-to-frequency converter, and energy
pulse outputs on a single chip. The CS5466 is designed
to accurately measure and calculate energy for single
phase, 2- or 3-wire power metering applications with
minimal external components.
The low-frequency pulse outputs, E1 and E2, provide
pulses at a frequency which is proprtional to the active
power and can be used to drive a stepper motor or a me-
chanical counter. Energy direction output, NEG,
indicates when pulse outputs E1 and E2 represent neg-
ative active power. The high-frequency pulse output
FOUT is designed to assist in system calibration.
The CS5466 has configuration pins which allow for direct
configuration of pulse output frequency, current channel
input range, and high-pass filter enable option.
The CS5466 also has a power-on reset function which
holds the part in reset until the supply reaches an oper-
able level.
