DESCRIPTION
FEATURES
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 co...
