Description
The CS5490 is a high-accuracy, two-channel, energy measure-
ment analog front end.
The CS5490 incorporates independent 4th order Delta-Sigma an-
alog-to-digital converters for both channels, reference circuitry,
and the proven EXL signal processing core to provide active, re-
active, and apparent energy measurement. In addition, RMS and
power factor calculations are available. Calculations are output
via a configurable energy pulse, or direct UART serial access to
on-chip registers. Instantaneous current, voltage, and power
measurements are also available over the serial port. The
two-wire UART minimizes the cost of isolation where required.
A configurable digital output provides energy pulses, zero-cross-
ing, energy direction, or interrupt functions. Interrupts can be
generated for a variety of conditions including voltage sag or
swell, overcurrent, and more. On-chip register integrity is assured
via checksum and write protection. The CS5490 is designed to in-
terface to a variety of voltage and current sensors, including shunt
resistors, current transformers, and Rogowski coils.
On-chip functionality makes digital calibration simple and ultra
fast to minimize the time required at the end of the customer pro-
duction line. Performance across temperature is ensured with an
on-chip voltage reference with low drift. A single 3.3V power sup-
ply is required, and power consumption is low at <13mW. To
minimize space requirements, the CS5490 is offered in a low-cost
16-pin SOIC package.
