Product details
Overview
MAX4211AEUE 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), supports 4V–28V input source voltage, operates from +2.7V to +5.5V supply, and achieves ±1.5% max current/power sensing accuracy - ideal for smart battery chargers and overpower circuit-breaker protection.
For engineers reviewing the MAX4211AEUE datasheet, MAX4211AEUE pinout, MAX4211AEUE application, or MAX4211AEUE equivalent, this page provides verified package mapping (16-pin TSSOP), confirmed pin functions, real-world use cases in battery safety and power-level detection, and validated alternative parts with documented functional differences.
Technical Context
The MAX4211AEUE implements a high-side sensing architecture using an internal 25:1 resistor-divider network (A/B/C variant), enabling direct measurement of load current without disrupting ground return paths. Its multiplier-based power output (POUT = k × VSENSE × VRS+) supports real-time power monitoring across wide common-mode ranges.
It integrates two uncommitted comparators with 1.21V reference output, open-drain outputs rated to 28V, and independent latch-enable (LE) and inhibit (INHIBIT) logic inputs - enabling configurable overcurrent/overpower/overvoltage detector circuits for circuit-breaker applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side power monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4211BEUE | Current-sense gain = 25.00 V/V; power-sense gain = 1.00 1/V - higher sensitivity for lower VSENSE ranges (e.g., 50mV full-scale) | Better suited for low-current applications where 150mV VSENSE_FS is impractical; same pinout and feature set | Select when load current sensing requires >16.67× gain to maximize ADC resolution at low currents |
| MAX4211CEUE | Current-sense gain = 40.96 V/V; power-sense gain = 1.64 1/V - highest gain option for ultra-low VSENSE (e.g., 100mV full-scale) | Optimized for minimal sense-resistor power loss in space-constrained designs; identical comparator/reference functionality | Choose for battery-powered systems needing maximum current resolution with <100mV sense voltage |
Compared with MAX4211BEUE and MAX4211CEUE, the MAX4211AEUE offers the lowest current-sense gain (16.67 V/V) and power-sense gain (0.667 1/V), making it optimal for mid-range current sensing where 150mV full-scale VSENSE balances accuracy and resistive loss - critical for 24V industrial power monitors.

FAQ
What is the function of the LE (Latch Enable) pin on the MAX4211AEUE?
The LE pin on the MAX4211AEUE is an active-high logic input that latches the states of COUT1 and COUT2 comparators when asserted. Once latched, the outputs remain asserted even if the fault condition clears, ensuring reliable fault capture in safety-critical systems like circuit breakers. The latch is reset only when LE is deasserted and the fault condition no longer exists. This behavior is fully specified in the MAX4211AEUE datasheet under Electrical Characteristics and Functional Diagram sections.
Does the MAX4211AEUE require external resistors for its current-sense divider network?
No, the MAX4211AEUE does not require external resistors for its current-sense divider network. As an "A" variant, it integrates a factory-trimmed 25:1 internal resistor-divider, eliminating the need for external components and reducing layout complexity. This is explicitly confirmed in the General Description section of the MAX4211AEUE datasheet and distinguishes it from D/E/F variants, which rely on external dividers for design flexibility.
What is the maximum common-mode voltage the MAX4211AEUE can handle at RS+?
The MAX4211AEUE supports a common-mode input voltage range of +4V to +28V at the RS+ pin, as guaranteed by output voltage error tests and confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables of the MAX4211AEUE datasheet. This allows safe operation in 24V automotive and industrial bus monitoring applications without additional level-shifting circuitry.
Can the MAX4211AEUE's comparators be used independently for overcurrent and overvoltage detection?
Yes, the MAX4211AEUE's two comparators (CIN1+/CIN1− and CIN2+/CIN2−) can be configured independently: one for overcurrent (referenced to IOUT or VSENSE) and the other for overvoltage (referenced to VRS+ via external resistor divider). Both share the 1.21V reference but accept independent input pairs, enabling simultaneous, decoupled fault detection - a capability verified in the Functional Diagram and Applications section of the MAX4211AEUE datasheet.
What is the supply current consumption of the MAX4211AEUE at +25°C and VCC = +5.5V?
The MAX4211AEUE draws 670µA typical supply current at +25°C and VCC = +5.5V, with a maximum of 960µA across the full –40°C to +85°C operating range. This value is measured under standard test conditions (VRS+ = 25V, VSENSE = 5mV) and is documented in the Electrical Characteristics table of the MAX4211AEUE datasheet, supporting low-power battery monitoring applications.
