MAX34407

SMBus 4-Channel Wide Dynamic Range

Power Accumulator

General Description

Features and Beneﬁts

The MAX34407 is a current and voltage monitor that

is specialized for determining power consumption. The

device has a wide dynamic range to allow it to accurately

measure power in systems that consume small to large

amounts of power. The device is configured and moni-

● Enables Code Optimization to Minimize Power

Consumption in Portable Platforms

• Four Power Monitors with Wide 66dB Dynamic

Range

• Measures Both Current and Voltage

• Low Power Consumption

tored with a standard I C/SMBus serial interface. The

• Slow Mode for Reduced Power Consumption

• Power-Down Mode

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. The samples are then multiplied to obtain a

power value and the power values are then accumulated.

Upon a command from the host, the device transfers the

accumulated power samples as well as the accumulation

count to a set of registers that the host can access. This

transfer occurs without missing a sample and allows the

host to retrieve the data not in real time, but at any time

interval.

● Minimizes Processor Overhead with Autonomous

Operation

• Per Channel 48-Bit Power Accumulators Capture

17 Minutes of Data at 1024 Samples per Second

• Per Channel 12-Bit Voltage Registers

● High-Integration Solution Minimizes Parts Count,

PCB Space, and BOM Cost

• Wide Current Common-Mode Range of 2.5V to 15V

• Low Full-Scale, Current-Sense Voltage of 100mV

• I C/SMBus Interface

Applications

● Tablets

● Ultra Notebooks

● Smartphones

• Temperature Range: -40°C to +85°C

• Small, 2.285mm x 2.185mm Footprint WLP Package

with 16 Bumps at 0.5mm Pitch

● Ease of Development

• Evaluation Kit with Advanced GUI Available

(MAX34407EVKIT#)

• Windows Driver Available
