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 measurement 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 monitoring in smart battery packs, overpower circuit breakers, 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 for VIN scaling, enabling flexible gain selection and design adaptation across varying VRS+ and load conditions.
Unlike the A/B/C variants with internal 25:1 dividers, the D/E/F family-including MAX4210DEUA+T-requires external resistors to set the VIN path, supporting full-scale input voltages of 0.16V to 1.10V and delivering power gain of 25.00 1/V. Its architecture avoids ground-loop disruption and maintains ±1.5% total output error over –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current-Sense Gain | 25.00 V/V - sets IOUT = 25 × VSENSE, enabling accurate current monitoring with 100mV full-scale sense voltage |
| Power-Sense Gain | 25.00 1/V - defines POUT = 25 × VSENSE × VIN, supporting direct analog power computation |
| VSENSE Full-Scale Voltage | 150 mV - maximum differential sense voltage before saturation; determines minimum RSENSE for target current range |
| Input Source Voltage Range | +4V to +28V - supports high-side sensing in 12V/24V industrial, automotive, and battery systems |
| Supply Voltage Range | +2.7V to +5.5V - compatible with single Li-ion, dual-cell, or 3.3V/5V logic rails |
| Supply Current | 380 µA - ultra-low quiescent current enables always-on monitoring in energy-sensitive applications |
| Bandwidth | 220 kHz - sufficient for transient power detection in switching loads and fast fault response |
Pinout & Package
MAX4210DEUA+T is housed in an 8-pin µMAX® package (3mm × 3mm), featuring exposed paddle for thermal performance. Pin 1 is GND; pins 2–3–6 are N.C.; pin 4 is VCC; pin 5 is RS+; pin 7 is RS−; pin 8 is POUT. No IOUT or REF pins - consistent with MAX4210D variant's simplified output architecture.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Ground reference | Common return for VCC, RS−, and POUT; must be low-impedance to minimize offset error |
| N.C. (Pins 2, 3, 6) | No connection | Not internally bonded; leave unconnected or tie to GND per layout best practice |
| VCC (Pin 4) | Power supply input | Accepts +2.7V to +5.5V; requires local 0.1µF ceramic bypass capacitor to GND |
| RS+ (Pin 5) | High-side voltage sense input | Connects to high side of external RSENSE; common-mode range up to +28V |
| RS− (Pin 7) | Load-side sense input | Connects to load side of RSENSE; differential input with ±5V max rating |
| POUT (Pin 8) | Analog power output | Voltage output proportional to VSENSE × VIN; drives 1MΩ load with <0.5Ω output impedance |
Key Features
| Feature | Design Value |
|---|---|
| Real-time power monitoring | Direct analog POUT output eliminates need for external ADC/microcontroller multiplication |
| ±1.5% max current-sense accuracy | Enables reliable overcurrent detection within tight tolerance bands without calibration |

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; 150mV VSENSE_FS | Limited to fixed VIN scaling; less flexible for wide VRS+ variation | Select when board space is constrained and VRS+ is stable near 25V |
| INA226AIDGST | I²C digital output; 16-bit ADC; integrated shunt amplifier and multiplier; 0.1% gain error | Requires MCU interface and firmware; no direct analog POUT | Select when digital telemetry, logging, or multi-channel monitoring is required |

FAQ
What is the primary function of the MAX4210DEUA+T?
The MAX4210DEUA+T is a high-side power and current monitor IC that generates an analog output voltage (POUT) proportional to the product of load current (measured differentially across an external sense resistor) and source voltage (VRS+). It enables real-time, ground-independent power measurement in battery-powered and industrial systems.
Does the MAX4210DEUA+T include an internal reference or comparators?
No. The MAX4210DEUA+T does not integrate a reference or comparators - those features are exclusive to the MAX4211 family. MAX4210DEUA+T is a dedicated analog multiplier with POUT output only, optimized for simplicity and low power (380µA supply current).
What is the significance of the 'D' suffix in MAX4210DEUA+T?
The 'D' in MAX4210DEUA+T denotes the external resistor-divider configuration for the VIN input path, enabling user-defined scaling of the source voltage before multiplication. This provides greater design flexibility than the internal 25:1 divider used in MAX4210A/B/C variants.
Can the MAX4210DEUA+T operate with a 3.3V supply and 24V common-mode input?
Yes. The MAX4210DEUA+T supports VCC from +2.7V to +5.5V and common-mode input (VRS+) from +4V to +28V. With a 3.3V supply, it maintains full functionality including ±1.5% accuracy and 220kHz bandwidth - ideal for 3.3V microcontroller systems monitoring 24V loads.
What package type and pin count does the MAX4210DEUA+T use?
The MAX4210DEUA+T uses the 8-pin µMAX® package (3mm × 3mm). It has six functional terminals: GND (Pin 1), VCC (Pin 4), RS+ (Pin 5), RS− (Pin 7), POUT (Pin 8), and three no-connect pins (Pins 2, 3, 6) - confirmed in Maxim's official pin description table for the µMAX variant.
