DESCRIPTION
The 78M6613 is a highly integrated IC for simplified
implementation of single-phase AC power measurement
into power supplies, smart appliances, and ot her
applications with embedded AC load monitoring and
control. It is packaged in a small, 5mm x 5mm, 32-pin QFN
package for optimal space savings.
At the measurement interface, the device provides four
analog inputs for interfacing to voltage and current sensors.
Voltages from the sensors are fed to our Single Converter
Technology that uses a 22-bit delta-sigma ADC,
independent
32-bit
compute engine (CE), digital
temperature
compensation,
and
precision
voltage
references to provide better than 0.5% power measurement
accuracy over a wide 2000:1 dynamic range.
The integrated MPU core and 32 KB of flash memory
provides a flexible means of configuration, post-processing,
data formatting, and interfacing to any host processor
through the UART interface and/or DIO pins. Complete
application firmware is available and can be preloaded into
the IC during manufacturing test. Alternatively, a complete
array of ICE, development tools, and programming libraries
are available to allow customization for each application.
