1 Introduction
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. Other key attributes of the PSU solution for the 78M6613 include:
• Integrated XY capacitors compensation algorithms and calibration techniques unique to PSUs for
measuring after the EMI filter (before bridge). Critical for a manufacturable solution and precision
accuracy over entire load range.
• Accumulation intervals based on number of AC-cycles with a minimum of 4 AC Cycles for real-time
feedback (15 Hz refresh rate).
• Dual-mode serial interface: 1-wire Auto-Reporting interface mode and 2-wire Command Response
interface mode.
• Low-latency alarms for SAG and AC dropout detection.
Fully functional demo code can be evaluated in an Evaluation Kit (EVK) and used as is in most
applications. It can also serve as starting base for customization and adaptation to different needs with an
optional Software Development Kit (SDK).
