Product details
Overview
MAX4211EEUE from Maxim Integrated is a full-featured high-side current and power monitor IC integrating a precision current-sense amplifier, 1.21V bandgap reference, and two open-drain comparators. It delivers analog outputs proportional to load current (IOUT) and power (POUT) with ±1.5% max accuracy, operates from +4V to +28V input common-mode voltage, supports 25.00V/V current gain and 25.00 1/V power gain, and targets circuit-breaker protection in battery-powered systems.
For engineers reviewing the MAX4211EEUE datasheet, MAX4211EEUE pinout, MAX4211EEUE application, or MAX4211EEUE equivalent, this page provides verified functional specifications, package mapping to 16-pin TSSOP, comparator interface details, real-world overload detection use cases, and validated alternative part selection guidance for high-side monitoring designs.
Technical Context
The MAX4211EEUE implements a high-side sensing architecture using an internal 25:1 resistor-divider network (variant E), enabling direct measurement of load current without ground-path disruption. Its multiplier-based power output (POUT = VSENSE × VIN × gain) combines sensed current and source voltage to generate a real-time analog power signal.
Two uncommitted comparators accept inputs referenced to the 1.21V internal reference and support overcurrent, overpower, and overvoltage detection with open-drain outputs rated to 28V - suitable for driving external high-side switches in fault-clearing circuits.

| Power-Sense Gain | 25.00 1/V - sets POUT = 25 × VSENSE × VIN, supporting accurate power calculation across 0.2V–1V IN range |
| Input Common-Mode Range | +4V to +28V at RS+ - allows direct connection to high-side bus voltages without level-shifting |
| Supply Voltage Range | +2.7V to +5.5V - compatible with standard 3.3V/5V logic supplies while monitoring higher-voltage loads |
| Reference Output | 1.21V ±10mV - stable internal bandgap reference used by comparators for threshold setting |
| Comparator Outputs | Open-drain, 28V-tolerant - enables direct interfacing with external MOSFET gates or pull-up to higher rail |
| Accuracy | ±1.5% max current/power sense error - guaranteed over -40°C to +85°C, critical for reliable fault detection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side current and power monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4211AEUE | Lower power-sense gain (0.667 1/V); uses internal 25:1 divider on RS+ path only | Better suited for high-VRS+ (>15V), low-VIN (<1V) applications where POUT scaling must remain linear at low input voltages | Select MAX4211AEUE when monitoring high-bus, low-input-power systems (e.g., 24V solar charge controllers with 0.3V–0.8V PV input) |
| MAX4211DEUE | Higher current-sense gain (16.67V/V); same 25:1 divider but different gain binning | Optimized for lower-current ranges (e.g., <5A with 50mΩ shunt), offering improved resolution at sub-100mV VSENSE | Choose MAX4211DEUE for precision low-current monitoring where 16.67V/V gain yields better SNR than 25.00V/V at 50mV FS |
Compared with MAX4211AEUE and MAX4211DEUE, the MAX4211EEUE provides balanced 25.00V/V and 25.00 1/V gains ideal for mid-range current/power applications (e.g., 1–10A loads at 12–24V), delivering optimal dynamic range and minimal gain mismatch error in closed-loop power regulation.

FAQ
What is the function of the REF pin on the MAX4211EEUE?
The REF pin on the MAX4211EEUE provides a stable 1.21V ±10mV bandgap reference output used internally by the comparators and available externally for threshold-setting or calibration. It sources/sinks up to 100µA while maintaining accuracy across -40°C to +85°C, eliminating the need for external reference ICs in MAX4211EEUE-based detector circuits.
Can the MAX4211EEUE monitor power in a 48V system?
No - the MAX4211EEUE's RS+ input is rated for +4V to +28V common-mode voltage per Absolute Maximum Ratings and Electrical Characteristics tables. For 48V bus monitoring, a level-shifting front-end or alternative device such as the MAX40080 (supports up to 65V) is required. Using MAX4211EEUE above 28V risks permanent damage.
How does the MAX4211EEUE differ from the MAX4210 series?
The MAX4211EEUE integrates two open-drain comparators and a 1.21V reference, whereas MAX4210 variants are simplified power monitors without comparators or reference. MAX4211EEUE also uses a 16-pin TSSOP package versus MAX4210's 6-pin TDFN or 8-pin µMAX, enabling more complex fault-detection functionality in the same family.
What is the purpose of the LE and INHIBIT pins on the MAX4211EEUE?
The MAX4211EEUE does not include LE (Latch Enable) or INHIBIT pins - those are present only on MAX4210D/E/F variants with external resistor-divider configurations. The MAX4211EEUE uses internal 25:1 division and lacks latch or inhibit control; its comparators operate continuously once powered.
Is the MAX4211EEUE pin-compatible with other MAX4211 variants like MAX4211BEUE?
Yes - all MAX4211 variants (A/B/C/D/E/F) share identical 16-pin TSSOP pinouts and package dimensions. The suffix 'E' denotes the 25.00V/V current gain and 25.00 1/V power gain bin; swapping to MAX4211BEUE changes only gain values (25.00V/V → 25.00V/V remains same, but power gain shifts to 1.00 1/V), requiring no PCB layout change.
