CS5467
1. OVERVIEW
The CS5467 is a CMOS power measurement integrated circuit utilizing four ?? analog-to-digital convert-
ers to measure two line voltages and two currents. Optionally, voltage2 channel can be used for temper-
ature measurement. It calculates active, reactive, and apparent power as well as RMS and peak voltage
and current. It handles other system-related functions, such as pulse output conversion, voltage sag, cur-
rent fault, voltage zero crossing, line frequency, and voltage tamper correction.
The CS5467 is optimized to interface to current transformers or shunt resistors for current measurement,
and to resistive dividers or voltage transformers for voltage measurement. Two full-scale ranges are pro-
vided on the current inputs to accommodate both types of current sensors. The CS5467’s four differential
inputs have a common-mode input range from analog ground (AGND) to the positive analog supply
(VA+).
An additional analog input (PFMON) is provided to allow the application to determine when a power failure
is in progress. By monitoring the unregulated power supply, the application can take any required action
when a power loss occurs.
An on-chip voltage reference (nominally 2.5 volts) is generated and provided at analog output, VREFOUT.
This reference can be supplied to the chip by connecting it to the reference voltage input, VREFIN. Alter-
natively, an external voltage reference can be supplied to the reference input.
Three digital outputs (E1, E2, E3) provide a variety of output signals and, depending on the mode select-
ed, provide energy pulses, power failure indication, or other choices.
The CS5467 includes a three-wire serial host interface to an external microcontroller or serial E 2 PROM.
Signals include serial data input (SDI), serial data output (SDO), serial clock (SCLK), and optionally a chip
select (CS), which allows the CS5467 to share the SDO signal with other devices. A MODE input is used
to control whether an E 2 PROM will be used instead of a host microcontroller.
