CS5464
1. OVERVIEW
The CS5464 is a CMOS power measurement integrated circuit utilizing four ?? analog-to-digital convert-
ers to measure line voltage, temperature, and current from up to two sources. It calculates active, reactive,
and apparent power as well as RMS and peak voltage and current. It handles other system-related func-
tions, such as pulse output conversion, voltage sag, current fault, voltage zero crossing, line frequency,
and tamper detection.
The CS5464 is optimized to interface to current transformers or shunt resistors for current measurement,
and to a resistive divider or voltage transformer for voltage measurement. Two full-scale ranges are pro-
vided on the current inputs to accommodate both types of current sensors. The second current channel
can be used for tamper detection or as a second current input. The CS5464’s three 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 CS5464 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 CS5464 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.
