78M6610+PSU - Single-phase measurement processor

Features

  • 24-Bit Measurement Processor
  • Up to four sensor inputs
  • UART, I²C, SPI and configurable DIO
  • 16-pin TSSOP and 24-pin TQFN options

Description

The 78M6610+PSU is a single-core energy measurement processor for single-phase power supplies. It is designed specifically for real-time monitoring at the input of AC-DC power converters used in data centers and IT server rooms. It is available in either a 24-pin QFN or 16-pin TSSOP package for optimal space savings.

 
The 78M6610+PSU provides four analog inputs (two differential and two single ended) for interfacing to voltage, current, and two optional temperature sensors. Scaled voltages from the sensors are fed to the single converter front-end utilizing a high-resolution delta-sigma converter. An embedded 24-bit energy measurement processor (EMP) and firmware performs all the necessary computation, compensation, and data formatting for accurate, real-time reporting to the host. With integrated flash memory, the 78M6610+PSU is a completely autonomous solution capable of storing nonvolatile data such as calibration coefficients and input configuration settings.
 
The 78M6610+PSU is designed to interface to the host processor via the UART interface. Alternatively, SPI or I²C may also be used. Supported current sensors include current transformers (CT) and resistive shunts.
