DESCRIPTION
The
Teridian
78M6618
is
a
highly
integrated
IC
for
independent monitoring and measurement of up to eight
single-phase AC outlets. With multiple host interface options,
an integrated LCD driver, and configurable I/Os, the device is
ideal for metered power distribution units (PDUs) and rack
enclosures for the data center, as well as intelligent power
strips and subpanels in the grid-friendly digital home.
At the measurement interface, the device provides 10 analog
inputs for interfacing to voltage and current sensors. Scaled
voltages from the sensors are fed to our Single Converter
Technology
that uses a 21-bit delta-sigma ADC, independent
32-bit compute engine (CE), digital temperature compensation,
and precision voltage references to provide better than 0.5%
accuracy over a wide 2000:1 dynamic range.
The integrated MPU core and 128KB of flash memory provides
a flexible means of configuration, postprocessing, data
formatting, interfacing to host processor through a UART or
SPI interface, displaying output data to an LCD, or using
DIO pins for intelligent relay control. Complete firmware for
common applications is available from Teridian and can be
loaded into the IC during manufacturing test. Alternatively, a
complete array of ICE, development tools, and programming
libraries are available to allow customization MPU code for
each application.
