Energy Measurement IC CS5466

All Power Measurement parts have Data Linearity of 0.1% over a 1000:1 Range

The CS5466 has configuration pins which allow for direct configuration of pulse output frequency, current-channel input range and high-pass filter enable option. It also has a power-on reset function which holds the part in reset until the supply reaches an operable level.

The low-frequency pulse outputs, E1 and E2, provide pulses at a frequency which is proportional to the active power and can be used to drive a stepper motor or mechanical counter. Energy direction output, NEG, indicates when pulse outputs E1 and E2 represent negative active power. The high-frequency pulse output FOUT is designed to assist in system calibration.
