Product details
Overview
MAX4210DEUA-T from Maxim Integrated is a high-side power and current monitor IC with external resistor-divider configuration, 25.00V/V current-sense gain, ±1.5% max current-sense accuracy, ±1.5% max power-sense accuracy, and 220kHz bandwidth - designed for real-time load power monitoring in battery-powered systems without ground-path interference.
For engineers reviewing the MAX4210DEUA-T datasheet, MAX4210DEUA-T pinout, MAX4210DEUA-T application, or MAX4210DEUA-T equivalent, this device supports precise analog power measurement in smart battery chargers, short-circuit protection circuits, and power-supply displays where input source voltage ranges from +4V to +28V and supply voltage operates from +2.7V to +5.5V.
Technical Context
The MAX4210DEUA-T implements a high-side current-sense amplifier that multiplies sensed load current (via external RSENSE) with source voltage (VRS+) to generate an analog POUT proportional to instantaneous power. It uses an external resistor-divider network on the IN input to configure power gain, distinguishing it from internal-divider variants (A/B/C).
This variant (D/E/F) supports VIN-based power computation (VPOUT ∝ VSENSE × VIN), enabling flexible scaling for applications requiring independent voltage sensing - unlike A/B/C versions that compute power as VSENSE × VRS+. Its 25.00V/V current gain and 25.00 1/V power gain are factory-trimmed and stable over –40°C to +85°C.
Key Specifications

| 4 (VCC) | Power supply input | Accepts +2.7V to +5.5V; requires local 0.1µF ceramic bypass capacitor to GND for stability |
| 5 (RS+) | High-side sense resistor top node | Connects to positive terminal of external RSENSE; common-mode voltage up to +28V |
| 7 (RS–) | High-side sense resistor bottom node | Connects to load side of RSENSE; differential input range ±5V relative to RS+ |
| 8 (POUT) | Analog power output | Voltage output proportional to VSENSE × VIN; drives 1MΩ loads with <0.5Ω output impedance |

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 |
|---|---|---|---|
| MAX4210AEUA | Internal 25:1 resistor-divider; fixed 16.67V/V current gain and 0.667 1/V power gain; same 8-pin µMAX package | Limited to VRS+-based power computation; no external VIN scaling; lower full-scale sensitivity | Select when design uses only RS+/RS– sensing and requires simplified BOM with no external resistors |
| INA226AIDGST | I²C digital output; 16-bit delta-sigma ADC; integrated shunt and temperature sensing; 2.7V–5.5V supply | Requires MCU interface and firmware; provides energy/charge accumulation; no analog POUT output | Select when digital telemetry, logging, or multi-parameter monitoring (voltage/current/power/temp) is required over analog simplicity |

FAQ
What is the function of the IN pin on the MAX4210DEUA-T?
The IN pin on the MAX4210DEUA-T accepts an external voltage signal (0.16V to 1.10V) used as the second multiplier input for power calculation - enabling VPOUT ∝ VSENSE × VIN instead of VSENSE × VRS+. This allows independent voltage sensing (e.g., from a divider off the main rail) and is unique to D/E/F variants. The MAX4210DEUA-T requires external resistors on IN to set full-scale scaling.
Does the MAX4210DEUA-T include built-in comparators or reference outputs?
No, the MAX4210DEUA-T does not include comparators or a reference output. Those features are exclusive to the MAX4211 family (e.g., MAX4211D). The MAX4210DEUA-T is a dedicated analog power/current monitor with only IOUT and POUT analog outputs. Reference generation and over-limit detection require external components or a MAX4211 variant.
What is the maximum common-mode voltage the MAX4210DEUA-T can tolerate on RS+?
The MAX4210DEUA-T supports a common-mode input range of +4V to +28V on the RS+ pin, verified per Absolute Maximum Ratings and Electrical Characteristics tables. This allows direct connection between a 24V battery and load without attenuation or level-shifting, maintaining high-side sensing integrity while rejecting ground noise.
How does the MAX4210DEUA-T achieve ±1.5% power-sense accuracy?
The MAX4210DEUA-T achieves ±1.5% max power-sense accuracy through factory-trimmed current-sense amplifier gain (25.00V/V), matched internal multiplier architecture, and temperature-stable biasing - confirmed across –40°C to +85°C in production testing. Total error includes gain, offset, and nonlinearity contributions, all bounded under defined conditions (e.g., VSENSE = 10mV–100mV, VIN = 0.2V–1V).
Can the MAX4210DEUA-T be used with a 3.3V supply and 12V load?
Yes, the MAX4210DEUA-T operates from +2.7V to +5.5V on VCC and tolerates +4V to +28V common-mode voltage on RS+, making it fully compatible with a 3.3V supply and 12V load. Its high common-mode rejection (80dB) and 220kHz bandwidth ensure accurate power measurement despite ground potential differences and switching noise in such configurations.
