SMBUS Dual Channel High Dynamic Range

MAX34427

Power Accumulator

General Description

Benefits and Features

The MAX34427 is a specialized current, voltage, and

power monitor used to determine power consumption of

systems. The device has a very wide dynamic range

(20,000:1) that allows for the accurate measurement of

power in such systems. The device is configured and

•

Enables Code Optimization to Minimize Power

Consumption

Two Power Monitors with Wide 86dB Dynamic

Range

Measures Both Current and Voltage

Ability to Measure Only Accumulated Current or

Accumulated Power

Reduced Power Consumption in Slow Accumulation

Mode

Power-Down Mode

Minimizes Processor Overhead with Autonomous

Operation

• Per Channel 56-Bit Power Accumulators Capture

2.27 Hours of Data at 2048 Samples per Second

• Per Channel 14-Bit Voltage Registers

•

monitored with a standard I C/SMBus serial interface.

The unidirectional current sensor offers precision high-

side operation with a low full-scale sense voltage. The

device automatically collects the current-sense and

voltage samples and then multiplies those values to

obtain a power value it then accumulates. Upon a

command from the host, the device transfers the

accumulated power samples, as well as the

accumulation count, to a set of registers accessible by

the host. This transfer occurs without missing a sample

and allows the host to retrieve the data not only in real-

time, but at any time interval.

High-Integration Solution Minimizes Part Count, PCB

Space, and BOM Cost

• 5μV to 100mV Current-Sense Voltage with

Current Common-Mode Range of 0.5V to 24V
