MAX4210DEUA+

Current Regulation/Management Overview

The MAX4210DEUA+ is a high-side power and current monitor from Analog Devices. It provides an analog output proportional to load power by multiplying source voltage and current. Key parameters include a supply voltage range of 2.7V to 5.5V, input source voltage up to 28V, and ±1.5% max accuracy for both current and power sensing. It features a 380µA supply current, 220kHz bandwidth, and comes in an 8-pin uMAX package.

Current Regulation/Management Feature Summary

• High-side current sensing capability that avoids ground path interference
• Analog output representing real-time load power consumption
• Integrated precision reference and comparators for system protection

Current Regulation/Management Applications

• Overpower circuit breakers
• Smart battery packs and chargers
• Short-circuit protection circuits
• Power-supply displays and measurement instrumentation

Current Regulation/Management Procurement Notes

Verify the specific suffix 'D' indicates the required accuracy grade and package variant against the official datasheet. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the + suffix denotes lead-free compliance before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when high-side monitoring is necessary to preserve the load's ground reference. The ±1.5% accuracy suits general power management applications. Consider the 28V input range for moderate voltage systems. Evaluate the 380µA quiescent current against battery life requirements for portable designs.

Current Regulation/Management Part Context

This device belongs to the MAX4210/MAX4211 family of low-cost, low-power monitors. It differs from the MAX4211 by lacking uncommitted comparators and a reference output. The uMAX package offers a compact surface-mount solution suitable for space-constrained electronic assemblies requiring precise power tracking.

Current Regulation/Management Replacement Considerations

The MAX4210EEUA+ serves as a direct functional substitute within the same family, offering similar high-side monitoring capabilities with potentially different accuracy grades. Verify pin compatibility and electrical parameter alignment before substitution.
