Analog Devices Inc./Maxim Integrated MAX4210EEUA

Overview

MAX4210EEUA from Maxim Integrated is a high-side power/current monitor IC that delivers an analog voltage output proportional to load power (V_SENSE × V_RS+) via internal analog multiplication. It features 25.00 V/V current-sense gain, ±1.5% max current-sense accuracy, and operates from +2.7V to +5.5V supply with 380µA quiescent current. Designed for battery-powered systems, it avoids ground-path disruption by sensing on the high side.

For engineers reviewing the MAX4210EEUA datasheet, MAX4210EEUA pinout, MAX4210EEUA application, or MAX4210EEUA equivalent, this device is selected for real-time power monitoring in space-constrained, low-power applications such as smart battery chargers and short-circuit protection circuits where precision high-side sensing and minimal board footprint are critical.

Technical Context

The MAX4210EEUA implements a dedicated analog multiplier architecture that multiplies the sensed current (via V_SENSE = V_RS+ − V_RS−) with the source voltage (V_RS+) to generate POUT - a voltage directly proportional to instantaneous load power. Its internal 25:1 resistor-divider network eliminates external components for gain configuration.

This variant (E suffix) uses an external resistor-divider network for flexible gain selection, distinguishing it from A/B/C versions with integrated dividers. It supports full-scale V_SENSE of 150mV and operates across a +4V to +28V common-mode input range while maintaining 220kHz bandwidth and 60dB minimum CMRR.

FAQ

What is the function of the POUT pin on the MAX4210EEUA?

The POUT pin on the MAX4210EEUA delivers an analog voltage output proportional to the instantaneous power consumed by the load (V_SENSE × V_RS+). With a fixed 25.00 1/V gain, POUT = 25 × V_SENSE × V_RS+. This output is ratiometric to V_RS+, enabling direct interface with ADCs or analog meters without additional scaling. For MAX4210EEUA, POUT settles within 10µs and supports capacitive loads up to 450pF.

Does the MAX4210EEUA require external resistors for gain configuration?

Yes - the MAX4210EEUA belongs to the "D/E/F" variant group and uses an external resistor-divider network to set its current-sense and power-sense gains. Unlike A/B/C variants with integrated 25:1 dividers, the E version relies on external resistors for gain flexibility. This allows designers to precisely tune sensitivity and optimize shunt resistor power loss, noise, and layout parasitics without changing the IC.

What is the operating temperature range for the MAX4210EEUA?

The MAX4210EEUA is specified for operation across the extended industrial temperature range of –40°C to +85°C. All electrical characteristics - including ±1.5% current-sense accuracy, 220kHz bandwidth, and 380µA supply current - are guaranteed over this full range. Thermal performance is validated with junction temperatures up to +150°C, supporting reliability in enclosed or thermally stressed environments.

Can the MAX4210EEUA monitor loads powered from 24V supplies?

Yes - the MAX4210EEUA supports a common-mode input voltage range of +4V to +28V on the RS+ pin, making it fully compatible with 24V systems. Its high-side architecture ensures accurate current and power measurement without disrupting the load's ground return path. When used with a 150mV full-scale V_SENSE, it maintains ±1.5% accuracy across the entire 24V range, verified in production testing and typical operating characteristics.

How does the MAX4210EEUA differ from the MAX4211 series?

The MAX4210EEUA is a simplified, low-cost power monitor without comparators or reference outputs, whereas the MAX4211 integrates two open-drain comparators and a 1.21V bandgap reference for autonomous overpower/overcurrent detection. MAX4210EEUA targets applications needing only analog outputs (IOUT/POUT) and minimal footprint, while MAX4211 suits designs requiring hardware-level fault response. Both share identical gain options and accuracy specs, but MAX4210EEUA consumes only 380µA vs. 670–1100µA for MAX4211 variants.
