Product details
Overview
MAX4210FEUA-T from Maxim Integrated is a high-side power and current monitor IC with 40.96V/V current-sense gain, 100mV full-scale sense voltage, ±1.5% current-sense accuracy, and 220kHz bandwidth. It operates from +2.7V to +5.5V supply and supports +4V to +28V common-mode input range, enabling real-time load power monitoring in battery-powered systems without ground-path interference.
For engineers reviewing the MAX4210FEUA-T datasheet, MAX4210FEUA-T pinout, MAX4210FEUA-T application, or MAX4210FEUA-T equivalent, this device serves as a precision analog multiplier for high-side current × voltage measurement in smart battery packs, short-circuit protection circuits, and power-supply displays where space-constrained 8-pin µMAX packaging and internal resistor-divider flexibility are critical.
Technical Context
The MAX4210FEUA-T implements a high-side current-sense amplifier paired with an analog multiplier architecture to generate POUT = VSENSE × VIN × GAIN (where GAIN = 40.96 1/V for F variant), using an external resistor-divider network on the IN input path. Its design avoids ground-loop disruption by sensing current upstream of the load.
It features rail-to-rail output swing capability (VOUT_MIN = 1.5mV at 10µA sink; VOUT_MAX = VCC − 0.25V), low 380µA supply current, and stable operation up to 450pF capacitive load - optimized for direct connection to ADC inputs or comparator thresholds in overload detection systems.
Key Specifications

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 | Fixed 25:1 internal resistor-divider; 150mV VSENSE_FS; 16.67V/V gain | Limited to fixed-gain designs with higher sense voltage; less flexible for low-shunt applications | Select when board space is constrained and gain requirements align with A/B/C variants |
| INA226AIDGST | I²C digital output; 16-bit ADC; integrated shunt; 0.1% gain error; 10MHz bandwidth | Requires MCU firmware support; adds communication overhead but enables multi-channel logging | Select when digital interface, higher accuracy, or system-level telemetry is prioritized over analog simplicity |
Compared with MAX4210AEUA and INA226AIDGST, the MAX4210FEUA-T offers superior analog flexibility via external divider tuning, lower power consumption than the INA226, and tighter full-scale sense voltage (100mV vs. 150mV) for improved resolution with ultra-low-value shunts.

FAQ
What is the function of the POUT pin on the MAX4210FEUA-T?
The POUT pin on the MAX4210FEUA-T delivers an analog voltage proportional to load power (VSENSE × VIN × 40.96), where VIN is derived from the external resistor-divider network. This output drives ADC inputs or comparator thresholds directly, supporting real-time power monitoring without additional signal conditioning. The MAX4210FEUA-T specifies POUT output swing from 1.5mV to VCC − 0.25V under defined load conditions.
Does the MAX4210FEUA-T include an internal reference voltage?
No, the MAX4210FEUA-T does not integrate a reference voltage. Unlike the MAX4211 series, it lacks the 1.21V bandgap reference output. Reference functionality must be provided externally if needed for comparator threshold setting or ADC reference scaling. The MAX4210FEUA-T relies entirely on its analog multiplier architecture and external resistor networks for gain and scaling.
What is the significance of the 'F' suffix in MAX4210FEUA-T?
The 'F' in MAX4210FEUA-T denotes the power-sense amplifier gain option of 40.96 1/V and confirms use of an external resistor-divider network on the VIN input path. This distinguishes it from A/B/C variants (internal 25:1 divider) and D/E variants (external divider with 16.67/25.00 1/V gain). The 'F' variant enables highest sensitivity for low-input-voltage monitoring scenarios.
Can the MAX4210FEUA-T operate with a 3.3V supply?
Yes, the MAX4210FEUA-T operates across +2.7V to +5.5V supply voltage, making 3.3V fully supported. At VCC = 3.3V, POUT maintains valid output swing down to 1.5mV (at 10µA sink) and up to VCC − 0.25V = 3.05V, ensuring compatibility with 3.3V ADC references and logic interfaces. Supply current remains 380µA typical at 3.3V per datasheet characterization.
How does the MAX4210FEUA-T handle overvoltage on the RS+ pin?
The MAX4210FEUA-T supports RS+ voltages from +4V to +28V continuously, with absolute maximum rating of +30V. Its high-side architecture inherently isolates the internal circuitry from RS+ potential, preventing latch-up or damage under normal operation. No external clamping is required for inputs within the specified common-mode range, though transient protection diodes may be added for ESD robustness beyond datasheet limits.
