Product details
Overview
MAX4211EETE-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 real-time analog outputs for load current (IOUT) and power (POUT), supports +4V to +28V input source voltage, operates from +2.7V to +5.5V supply, and achieves ±1.5% max current-sense accuracy. It is used in smart battery chargers and overpower circuit-breaker protection.
For engineers reviewing the MAX4211EETE-T datasheet, MAX4211EETE-T pinout, MAX4211EETE-T application, or MAX4211EETE-T equivalent, this page provides verified pin functions, gain-specific accuracy data, comparator interface behavior, thermal performance across -40°C to +85°C, and validated alternatives for overcurrent/overpower detection designs.
Technical Context
The MAX4211EETE-T implements a precision analog multiplier architecture that computes POUT = VSENSE × VIN × 25.00, where VIN is derived from an external resistor divider on RS+/RS− (for A/B/C variants) or applied directly to the IN pin (for D/E/F variants). Its current-sense amplifier uses a high-side topology to avoid ground-path disruption.
It integrates two uncommitted comparators with 5mV hysteresis, rail-to-rail common-mode input range (0.1V to VCC − 1.15V), and open-drain outputs rated to 28V - enabling direct drive of high-side MOSFET gates in circuit-breaker applications without level-shifting.

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 |
|---|---|---|---|
| MAX4211DET | Same 16-pin TQFN package; 16.67V/V current gain and 16.67 1/V power gain; lower full-scale sensitivity | Better suited for higher-current (>15A) sensing with 150mV VSENSE_FS; less sensitive to noise in low-power systems | Select MAX4211DET when designing for ≥15A loads with 15mΩ sense resistors and relaxed accuracy requirements |
| INA226AIDGST | 16-bit delta-sigma ADC with I²C interface; 1% current/power accuracy; no integrated comparators or reference | Requires host MCU for processing and decision logic; supports configurable averaging and alert registers | Choose INA226AIDGST when digital telemetry, logging, or adaptive thresholding is required instead of autonomous analog protection |
Compared with MAX4211EETE-T, MAX4211DET offers lower gain for higher-current applications but lacks the 25.00V/V precision needed for sub-10A monitoring, while INA226AIDGST trades autonomous analog response for digital configurability and higher resolution at the cost of added firmware complexity and latency.

FAQ
What is the exact current-sense gain of MAX4211EETE-T and how is it used in design?
The MAX4211EETE-T has a fixed current-sense amplifier gain of 25.00V/V, meaning IOUT = 25 × VSENSE. This gain is factory-trimmed and specified over −40°C to +85°C with ±1.5% max error. In design, it determines the sense-resistor value needed to achieve desired full-scale output - e.g., a 10mΩ resistor yields 100mV at 10A, producing 2.5V at IOUT. The gain is used directly in analog feedback loops or ADC scaling without software correction.
Does MAX4211EETE-T require external components to operate as a power monitor?
Yes, MAX4211EETE-T requires an external sense resistor (RSENSE) between RS+ and RS−, and for D/E/F variants like MAX4211EETE-T, an external resistor divider from RS+ to IN to scale the source voltage into the 0.16V–1.10V input range. A 0.1µF ceramic capacitor from VCC to GND is mandatory. No external reference or comparator pull-ups are required, as REF is provided internally and COUT1/COUT2 are open-drain.
How do the comparators in MAX4211EETE-T interface with external high-voltage circuits?
The comparators in MAX4211EETE-T feature open-drain outputs (COUT1/COUT2) rated to withstand up to +28V on the pull-up side. This allows direct connection to a 12V or 24V rail through a pull-up resistor, enabling direct drive of the gate of a high-side N-channel MOSFET without level-shifting circuitry. The 5mV hysteresis prevents chatter during slow threshold crossings, and the LE pin allows latching of fault events until manually cleared.
What is the role of the IN pin in MAX4211EETE-T and how does it differ from MAX4211A/B/C?
In MAX4211EETE-T (an E variant), the IN pin accepts the scaled-down version of VRS+ - typically derived from an external resistor divider - and serves as the second input to the analog multiplier for power calculation (POUT ∝ VSENSE × VIN). Unlike MAX4211A/B/C, which embed a 25:1 internal divider and route VRS+ directly to the multiplier, the E variant gives designers full flexibility to set the division ratio and optimize for specific voltage ranges or accuracy trade-offs.
Can MAX4211EETE-T be used in battery-powered systems with strict quiescent current limits?
Yes, MAX4211EETE-T draws only 670µA typical (960µA max) supply current at +5.5V, making it suitable for always-on battery monitoring in smart peripherals and portable equipment. Its supply current remains stable across temperature (−40°C to +85°C) and input common-mode voltage (4V–28V), and the INHIBIT pin allows complete shutdown to <1µA during sleep modes - preserving battery life while retaining fast wake-up capability.
