The 78M6613 is a highly integrated IC for simplified implementation of single-phase AC power measurement into power supplies, smart appliances, and other 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.
The 78M6613 PSU Firmware is a turnkey energy measurement solution optimized for use in AC power-supply units (PSUs). At the sensor interface, the 78M6613 with PSU Firmware supports one voltage sense input, one current sense input, and an optional input for an external thermistor voltage measurement. At the host interface, ready-to-use data is available over a low baud-rate serial interface for minimal cost of data isolation.
The 78M6613 HPL Firmware is a turnkey energy measurement solution optimized for use in AC high power load units (HPLs), also known as "split-phase." At the sensor interface, the 78M6613 with HPL Firmware supports two voltage sense inputs and two current sense inputs. At the host interface, ready-to-use data is available over a low baud-rate serial interface for minimal cost of data isolation.
