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 I

may also be used. Supported current sensors include

Current Transformers (CT) and Resistive Shunts.
