4-Channel, Single Phase Power/Energy IC - CS5467U - Cirrus Logic, Inc.
Austin, TX, USA
4-Channel, Single Phase Power/Energy IC CS5467U
The CS5480 is part of the CS548x/9x family of high performance analog front end solutions for energy measurement with two (CS5490), three (CS5480) or four (CS5484) 24-bit analog to digital converters. It provides high-accuracy energy measurement at a very low price, and on-chip energy calculations and fast on-chip calibration speeds product development cycles. Flexibility in current sensors, serial communications and digital outputs ensures that the CS5480 is a fit for any application requiring high-accuracy energy measurement at a very low price. Features Superior analog performance with ultra-low noise level and high SNR Energy measurement accuracy of 0.1% over 4000:1 dynamic range Current RMS measurement accuracy of 0.1% over 1000:1 dynamic range 3 independent 24 bit, 4th order Delta Sigma modulators for voltage and current measurements 3 configurable digital outputs for energy pulses, zero crossing or energy direction Supports shunt resistor, CT and Rogowski coil current sensors Overcurrent, voltage sag and voltage swell detection UART / SPI serial interface Internal register protection via checksum and write-protection On-chip voltage reference (25 ppm/°C typ.) Single 3.3V power supply Low power consumption: < 13mW CS5480: 4mm x 4mm 24-pin QFN ackage On-chip measurements / calculations: Active, reactive and apparent power RMS voltage and current Power factor and line frequency Instantaneous voltage, current and power
