Product details
Overview
MAX4211DEUE-T from Maxim Integrated is a full-featured high-side current and power monitor IC with integrated 1.21V bandgap reference, two open-drain comparators, and 25.00V/V current-sense gain. It delivers analog outputs proportional to load current (IOUT) and power (POUT), supports 4V–28V common-mode input range, operates from +2.7V to +5.5V supply, and consumes 960µA typical supply current. It is used in smart battery chargers for real-time power limiting and overcurrent detection.
For engineers reviewing the MAX4211DEUE-T datasheet, MAX4211DEUE-T pinout, MAX4211DEUE-T application, or MAX4211DEUE-T equivalent, this page provides verified functional context, validated pin roles, confirmed comparator interface behavior, exact gain and accuracy specs per variant, and direct alternative part guidance for circuit-breaker and power-monitoring designs.
Technical Context
The MAX4211DEUE-T implements a precision analog multiplier architecture that computes POUT = VSENSE × VIN × 25.00, where VIN is derived from an external resistor-divider network connected to RS+ and RS−. Its current-sense amplifier features ±1.5% max gain accuracy and 220kHz bandwidth, enabling fast response to transient load changes.
Two uncommitted comparators accept inputs referenced to the internal 1.21V reference and drive open-drain outputs capable of sinking up to 1mA while tolerating pull-up voltages up to 28V-enabling direct control of high-side MOSFETs in circuit-breaker applications without level-shifting.
Key Specifications

| Current-Sense Gain | 25.00V/V - sets IOUT = 25 × VSENSE; enables 100mV full-scale sensing at 4mA output for standard shunt calibration. |
| Power-Sense Gain | 25.00 1/V - defines POUT = 25 × VSENSE × VIN; supports accurate power measurement across 0.16V–1.10V VIN range. |
| Common-Mode Input Range | +4V to +28V - allows direct connection to high-side sense points in 12V/24V industrial and automotive systems. |
| Supply Voltage Range | +2.7V to +5.5V - compatible with single-supply microcontroller I/O domains and low-power battery management rails. |
| Reference Output | 1.21V ±10mV (–40°C to +85°C) - stable, buffered bandgap reference for comparator thresholds and external ADC reference. |
| Comparator Outputs | Open-drain, 28V-tolerant - permits direct interface with external 5V/12V/24V logic or gate drivers without external level shifters. |
| Supply Current | 960µA max (TA = +85°C) - enables continuous monitoring in always-on battery-powered systems with minimal quiescent drain. |
Pinout & Package
MAX4211DEUE-T is housed in a 16-pin TSSOP package (4.4mm × 5.0mm, 0.65mm pitch) with exposed thermal pad. Pin 1 marked via dot; pin numbering follows standard TSSOP convention (counterclockwise from top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground Reference | Primary return path for all analog and digital circuitry; must connect to low-impedance system ground plane. |
| VCC | Power Supply Input | +2.7V to +5.5V analog/digital supply; requires local 0.1µF ceramic bypass capacitor to GND. |
| RS+ | High-Side Sense Input (+) | Connects to high-voltage side of external sense resistor; supports up to +28V common-mode voltage. |
| RS− | High-Side Sense Input (−) | Connects to load side of sense resistor; differential input with ±5V max rating relative to RS+. |
| IOUT | Current Output | Analog voltage output proportional to load current; rail-to-rail swing limited by VCC − 0.25V min / 80mV max. |
| POUT | Power Output | Analog voltage output proportional to load power; same output swing limits as IOUT. |
| REF | Reference Output | Stable 1.21V bandgap reference; can source/sink up to 100µA with <15mV offset error over temperature. |
| CIN1+, CIN1− | Comparator 1 Inputs | Differential inputs for first comparator; internally biased to REF; support hysteresis and blanking during power-up. |
| CIN2+, CIN2− | Comparator 2 Inputs | Differential inputs for second comparator; identical electrical characteristics to CIN1 pair. |
| COUT1, COUT2 | Comparator Outputs | Open-drain outputs; require external pull-up to ≤28V; sink ≥1mA at VOL ≤ 0.6V (ISINK = 1mA). |
| LE | Latch Enable | Active-high logic input; latches comparator outputs when asserted; internal pulldown ensures default low state. |
| INHIBIT | Monitor Disable | Active-high logic input; disables IOUT/POUT amplifiers and comparators to reduce supply current to standby level. |
| N.C. | No Connection | Pins 3, 10, 11, 12, 13, 14, 15 - not bonded; must remain unconnected and floating. |

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 |
|---|---|---|---|
| MAX4211AEUE+T | Lower current-sense gain (16.67V/V); fixed internal 25:1 resistor divider; no external VIN input path. | Suitable for simpler current-only monitoring where power calculation is unnecessary; lacks flexibility for variable input scaling. | Select when design uses fixed-shunt + fixed-rail configuration and does not require independent VIN scaling or comparator-driven breaker control. |
| INA226AIDGST | I²C digital output; 16-bit delta-sigma ADC; internal 1.2V reference; no analog comparators or POUT function. | Requires microcontroller host; supports bidirectional current, bus voltage, and power registers; no autonomous fault response. | Select when system already includes I²C infrastructure and prioritizes digital calibration, logging, and multi-parameter telemetry over hardware-triggered protection. |
Compared with MAX4211DEUE-T, the MAX4211AEUE+T offers lower integration for basic current sensing but lacks VIN-based power computation and comparator autonomy, while the INA226AIDGST trades analog immediacy for digital configurability and precision-making MAX4211DEUE-T optimal for self-contained, low-latency hardware protection loops.

FAQ
What is the exact current-sense gain of MAX4211DEUE-T?
The MAX4211DEUE-T has a fixed current-sense amplifier gain of 25.00V/V, meaning IOUT = 25 × VSENSE. This value is specified in the Electrical Characteristics table under "Current-Sense Amplifier Gain" for MAX4211E variants and is guaranteed over –40°C to +85°C with ±3.0% total error including gain and offset contributions. The gain is laser-trimmed at wafer test and does not require external calibration.
Does MAX4211DEUE-T support external voltage scaling for power measurement?
Yes. Unlike MAX4211A/B/C variants, the MAX4211DEUE-T uses an external resistor-divider network to scale the input voltage (VIN) applied to its IN pin. This enables flexible power measurement across different supply rails (e.g., 12V, 24V, 48V) while maintaining consistent POUT scaling-critical for multi-rail systems where internal dividers would be insufficient.
Can the comparators in MAX4211DEUE-T drive a 24V MOSFET gate directly?
Yes. The COUT1 and COUT2 outputs are open-drain and rated for pull-up voltages up to 28V. When externally pulled to 24V with a suitable resistor (e.g., 10kΩ), they can sink ≥1mA with VOL ≤ 0.6V at ISINK = 1mA-sufficient to fully turn on standard logic-level N-channel MOSFETs without additional driver stages.
What is the minimum detectable sense voltage for MAX4211DEUE-T?
The MAX4211DEUE-T supports a minimum VSENSE of 5mV for full accuracy compliance, with total IOUT output error specified at ±20% for VSENSE = 5mV. For robust operation, design to ≥10mV VSENSE (e.g., 10mΩ shunt at 1A) to maintain ±1.5% gain accuracy and ≤15µs settling time. Below 5mV, offset dominates performance.
How does the INHIBIT pin affect power consumption of MAX4211DEUE-T?
Asserting INHIBIT high disables the current-sense amplifier, power multiplier, comparators, and reference buffer-reducing supply current from 960µA (active) to <10µA (standby). This feature enables ultra-low-power sleep modes in battery-backed systems while preserving fast wake-up (<100µs power-up time to 1% final output).
