Overview

The MAX34417ENE+T is a high-side current and voltage monitor designed to provide a high-integration solution for multi-rail power monitoring. It features four independent channels with 56-bit power accumulators that enable autonomous operation and minimize host processor overhead by storing up to 4.55 hours of data at 1024 samples per second.

Why Choose This Part

This device offers a wide 86dB dynamic range and can sense current-sense voltages as low as 5 microvolts. Its autonomous accumulation features allow for long-term power monitoring without frequent polling, reducing system bus traffic and host power consumption.

Applications

Mobile Device Power Tracking
Ideal for smartphones and tablets to monitor multi-rail power consumption across CPU, GPU, and peripheral rails with high dynamic range.
Battery Life Optimization
Utilizes a low full-scale current-sense voltage of 100mV to minimize power loss while providing accurate accumulation for battery gas gauging.
Server Power Management
Monitors voltage and current on supply rails from 0.5V to 20V to ensure system stability and efficiency.
High-Density Consumer Electronics
Fits into tight footprints using a 16-WLP package for space-constrained wearable and portable designs.
