Product details
Overview
MAX4210BEUA+ from Maxim Integrated is a high-side current and power monitor IC with 25.00V/V current-sense gain, ±1.5% max current-sense accuracy, and 150mV full-scale sense voltage. It operates from +2.7V to +5.5V supply and supports input common-mode voltages up to +28V, enabling real-time load monitoring in battery-powered systems without ground-path interference.
For engineers reviewing the MAX4210BEUA+ datasheet, MAX4210BEUA+ pinout, MAX4210BEUA+ application, or MAX4210BEUA+ equivalent, this device is selected for high-accuracy, low-power, space-constrained high-side sensing in smart battery packs, overload protection circuits, and power-supply displays where analog output scaling and temperature-stable gain are critical.
Technical Context
The MAX4210BEUA+ integrates a precision high-side current-sense amplifier with an internal 25:1 resistor-divider network (variant B), eliminating external components for VRS+ scaling. Its analog multiplier architecture delivers POUT = GP × VSENSE × VIN, where GP = 1.00 1/V for this variant.
It features a 220kHz bandwidth, 380µA supply current at +5.5V, and operates across –40°C to +85°C. The device outputs two independent analog signals: IOUT proportional to load current and POUT proportional to instantaneous power - both referenced to ground and compatible with standard ADC inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current-Sense Gain | 25.00V/V - sets IOUT = 25 × VSENSE; enables 150mV full-scale sensing with 3.75V output swing |
| Power-Sense Gain | 1.00 1/V - yields POUT = 1.00 × VSENSE × VIN; provides direct mW-to-V scaling when VIN = 1V |
| Current-Sense Accuracy | ±1.5% (max) - guarantees measurement error ≤ ±1.5% over –40°C to +85°C, critical for battery fuel gauging |
| Supply Voltage Range | +2.7V to +5.5V - compatible with single Li-ion, dual-cell alkaline, or 3.3V/5V system rails |
| Common-Mode Input Range | +4V to +28V - supports high-side sensing in 12V/24V automotive, industrial, and telecom power rails |
| Supply Current | 380µA (typ at +5.5V) - enables always-on monitoring in energy-sensitive portable applications |
| Bandwidth | 220kHz - captures fast transient load changes, suitable for dynamic power profiling and short-circuit detection |
Pinout & Package
MAX4210BEUA+ is housed in an 8-pin µMAX® package (3mm × 3mm, 0.5mm pitch), thermally enhanced with exposed paddle. Pin 1 is marked by a dot; pins 2, 3, and 6 are No Connect (N.C.) internally.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all analog outputs and internal circuitry; must be low-impedance connection |
| 2, 3, 6 | N.C. | No internal connection; leave unconnected or tie to GND per layout best practice |
| 4 | VCC | +2.7V to +5.5V supply input; requires 0.1µF ceramic bypass capacitor to GND |
| 5 | RS+ | High-side terminal of sense resistor; connects to power rail and internal 25:1 divider (variant B) |
| 7 | RS– | Load-side terminal of sense resistor; differential input for current measurement |
| 8 | POUT | Analog power output (ground-referenced); scales linearly with VSENSE × VIN |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 25:1 resistor-divider | Eliminates external scaling resistors for RS+ input, reducing BOM count and layout area in compact designs |
| ±1.5% current-sense accuracy | Ensures reliable load current reporting across temperature and supply voltage variations without calibration |
| 150mV full-scale sense voltage | Minimizes I²R loss in shunt resistor while maintaining SNR > 60dB for typical 10mΩ–100mΩ shunts |
| 220kHz signal bandwidth | Supports accurate capture of pulsed loads (e.g., motor startup, RF PA bursts) without phase lag or distortion |
| +4V to +28V common-mode range | Enables direct high-side monitoring on 12V/24V bus without level-shifting or isolation components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side current and power monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4210AEUA+ | 16.67V/V current gain; 150mV full-scale sense voltage; same µMAX package and pinout | Lower gain reduces output swing for same shunt voltage; suited for higher-current, lower-precision use cases | Select when lower sensitivity suffices and tighter gain tolerance is not required |
| MAX4210CEUA+ | 40.96V/V current gain; 100mV full-scale sense voltage; same µMAX package and pinout | Higher gain improves resolution for low-current sensing but limits max shunt voltage to 100mV | Select for ultra-low-power applications requiring <1mA sensing resolution with minimal shunt loss |
Compared with MAX4210AEUA+ and MAX4210CEUA+, the MAX4210BEUA+ offers balanced sensitivity (25V/V) and full-scale headroom (150mV), making it optimal for mid-range current monitoring where both accuracy and shunt efficiency matter - e.g., 1A–10A battery or PSU applications.

FAQ
What is the function of the RS+ and RS– pins on the MAX4210BEUA+?
The RS+ and RS– pins form the differential input for the high-side current-sense amplifier in the MAX4210BEUA+. RS+ connects to the high-voltage side of the external sense resistor (and to the internal 25:1 divider), while RS– connects to the load side. Together, they measure VSENSE = VRS+ − VRS–, which the MAX4210BEUA+ converts into proportional IOUT and POUT analog outputs.
Does the MAX4210BEUA+ require external resistors for voltage scaling?
No. The MAX4210BEUA+ is the "B" variant and integrates a factory-trimmed 25:1 resistor-divider network for the RS+ input, eliminating the need for external scaling components. This simplifies design, improves accuracy, and saves PCB area compared to variants like MAX4210DEUA+ that require external dividers.
What is the full-scale sense voltage and corresponding current-sense gain for MAX4210BEUA+?
The MAX4210BEUA+ has a 150mV full-scale sense voltage (VSENSE_FS) and a current-sense amplifier gain of 25.00V/V. This means a 150mV differential input produces a 3.75V IOUT output (25 × 0.15V), supporting accurate current measurement with minimal shunt power loss.
Can the MAX4210BEUA+ monitor power in systems with variable supply voltage?
Yes. The MAX4210BEUA+ multiplies VSENSE by VIN (applied to the IN pin) to generate POUT. For variant B, the power gain is 1.00 1/V, so POUT = 1.00 × VSENSE × VIN. When VIN tracks the monitored supply, POUT directly reflects instantaneous load power - even under varying rail conditions.
What is the operating temperature range and supply current of the MAX4210BEUA+?
The MAX4210BEUA+ is specified for operation from –40°C to +85°C and draws only 380µA (typical) from a +5.5V supply. Its low quiescent current and wide temperature range make it suitable for always-on monitoring in automotive, industrial, and portable equipment where reliability and power efficiency are essential.
