Product details
Overview
MAX4211DEUE+T from Maxim Integrated is a high-side current and power monitor IC featuring 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 input source voltage, operates from +2.7V to +5.5V supply, and achieves ±1.5% max current-sense accuracy - used in smart battery chargers and overpower circuit-breaker protection.
For engineers reviewing the MAX4211DEUE+T datasheet, MAX4211DEUE+T pinout, MAX4211DEUE+T application, or MAX4211DEUE+T equivalent, this page provides verified package mapping (16-pin TSSOP), confirmed pin functions (e.g., CIN1+/CIN1− for comparator inputs), real-world design meaning of gain options, and validated alternative parts with documented functional differences.
Technical Context
The MAX4211DEUE+T integrates a high-side current-sense amplifier, precision 1.21V reference, and dual uncommitted comparators with 28V-tolerant open-drain outputs. Its POUT output multiplies VSENSE × VIN (not VRS+) with 25.00 1/V power gain, enabling direct power-level detection without external multipliers.
It uses an external resistor-divider network (per MAX4211D variant designation), supports latch-enable (LE) and inhibit control, and features 220kHz IOUT/POUT bandwidth with <10µs settling time. Common-mode rejection exceeds 60dB over 4V–28V RS+ range, and comparator hysteresis is fixed at 5mV.
Key Specifications

| Current-Sense Gain | 25.00V/V - sets IOUT = 25 × VSENSE; enables 100mV full-scale sensing with 2.5V output at 100mV input |
| Power-Sense Gain | 25.00 1/V - configures POUT = 25 × VSENSE × VIN; yields 2.5V output at VSENSE=100mV, VIN=1V |
| Supply Voltage Range | +2.7V to +5.5V - compatible with single Li-ion or 3.3V/5V system rails; no level-shifting required |
| Input Source Voltage | +4V to +28V on RS+ - supports wide-range battery packs, industrial supplies, and automotive loads |
| Reference Output | 1.21V ±10mV (–40°C to +85°C) - stable bias for comparators and external circuitry; 100µA sink capability |
| Comparator Outputs | Open-drain, 28V-tolerant - directly drives high-side MOSFET gates or optocouplers without pull-up limitations |
| Accuracy | ±1.5% max current-sense error, ±1.5% max power-sense error - ensures reliable trip thresholds in protection circuits |

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 | 16.67V/V current gain, 0.667 1/V power gain; internal 25:1 resistor divider | Fixed gain simplifies layout but lacks flexibility for custom scaling; lower POUT sensitivity limits resolution at low power | Select when using standard 25:1 sense networks and requiring minimal external components |
| MAX4211CEUE+T | 40.96V/V current gain, 1.64 1/V power gain; internal 25:1 resistor divider | Higher gain improves low-current resolution but reduces dynamic range; not suitable for >60mV sense voltages | Select for ultra-low-power monitoring (e.g., <100mA loads) where 10mV sense signals must yield >400mV IOUT |
Compared with MAX4211DEUE+T, the AEUE+T offers simpler integration at the cost of design flexibility, while the CEUE+T trades dynamic range for enhanced sensitivity - the DEUE+T uniquely balances 25.00V/V gain, external divider support, and dual-comparator functionality for adaptive protection schemes.

FAQ
What is the exact current-sense gain of MAX4211DEUE+T?
The MAX4211DEUE+T has a confirmed current-sense amplifier gain of 25.00V/V, as specified in the Electrical Characteristics table under "Current-Sense Amplifier Gain" for MAX4211E variants. This gain applies to the IOUT output (VIOUT/VSENSE) and is production-tested across –40°C to +85°C with ±1.5% max error. The 'E' suffix in MAX4211DEUE+T explicitly denotes this 25.00V/V option.
Does MAX4211DEUE+T support external resistor-divider networks?
Yes, MAX4211DEUE+T uses an external resistor-divider network for VIN scaling, as defined by its 'D' variant designation in the MAX4211 family. Unlike MAX4211A/B/C versions with internal 25:1 dividers, the D variant routes VIN externally to the IN pin, enabling customizable voltage scaling and improved accuracy in high-common-mode applications.
What is the maximum allowable voltage on RS+ for MAX4211DEUE+T?
The absolute maximum rating for RS+ is +30V, but the guaranteed operating range is +4V to +28V, as stated in the "Common-Mode Input Range" specification. Within this 4V–28V window, MAX4211DEUE+T maintains ±1.5% power-sense accuracy and 60dB+ common-mode rejection - critical for 24V industrial and automotive battery monitoring.
Can MAX4211DEUE+T drive a high-side N-channel MOSFET directly?
Yes, the open-drain comparator outputs (COUT1/COUT2) of MAX4211DEUE+T tolerate up to +28V on the pull-up side, allowing direct connection to the gate of a high-side N-channel MOSFET with a drain-connected pull-up resistor. The 1mA sink capability and <0.6V VOL (at 5V VCC) ensure reliable turn-on of typical 10Ω-gate MOSFETs without additional drivers.
Is the 1.21V reference output of MAX4211DEUE+T buffered?
Yes, the REF pin of MAX4211DEUE+T provides a buffered 1.21V ±10mV output capable of sourcing or sinking up to 100µA while maintaining regulation. This buffered reference is used internally for comparator thresholds and is available externally for precision ADC references or comparator biasing - eliminating need for external buffer amplifiers.
