Product details
Overview
MAX4210CETT+T from Maxim Integrated is a high-side power/current monitor IC with integrated 25:1 resistor-divider, delivering analog POUT proportional to load power (VSENSE × VRS+). It features 1.64 1/V power gain, ±1.5% max power-sense accuracy, 220kHz bandwidth, and operates from +4V to +28V input source voltage - ideal for smart battery pack power monitoring and overload protection in space-constrained portable systems.
For engineers reviewing the MAX4210CETT+T datasheet, MAX4210CETT+T pinout, MAX4210CETT+T application, or MAX4210CETT+T equivalent, this page delivers verified package mapping (6-pin TDFN-EP), exact gain calibration (1.64 1/V), supply current (380µA), temperature range (–40°C to +85°C), and validated alternatives for high-side power sensing in battery management and circuit-breaker designs.
Technical Context
The MAX4210CETT+T implements a precision analog multiplier architecture that multiplies high-side current-sense voltage (VSENSE) by the sensed source voltage (VRS+) to generate a real-time power output (POUT). Its internal 25:1 resistor-divider eliminates external components while maintaining full-scale operation at VSENSE = 100mV and VRS+ = 25V.
It uses a dedicated high-side current-sense amplifier with 60dB common-mode rejection (CMRP) and operates independently of ground path integrity - enabling accurate monitoring in battery-powered systems without disrupting load grounding. The device supports fast settling (10µs to 1% for POUT) and stable capacitive loading up to 450pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
MAX4210CETT+T is housed in a thermally enhanced 6-pin TDFN-EP (3mm × 3mm) package with exposed paddle for improved thermal dissipation. Pin 2 is No Connection (N.C.) and must remain unconnected.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for internal circuitry and output stage; connects to PCB ground plane |
| 2 | N.C. | No internal connection; must be left floating or tied to GND per layout best practice |
| 3 | VCC | +2.7V to +5.5V supply input; requires 0.1µF ceramic bypass capacitor to GND |
| 4 | RS+ | High-side power rail connection; senses common-mode voltage up to +28V |
| 5 | RS− | Load-side sense resistor terminal; forms differential pair with RS+ for current measurement |
| 6 | POUT | Analog power output; voltage proportional to instantaneous load power (VSENSE × VRS+) |

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 |
|---|---|---|---|
| MAX4210AETT+T | Lower power gain (0.667 1/V); same package, accuracy, and bandwidth | Better suited for higher-power systems (>50W) where POUT scaling must avoid saturation at lower VSENSE | Select when full-scale POUT must remain ≤2.5V at VSENSE = 100mV and VRS+ = 25V |
| MAX4210BETT+T | Medium power gain (1.00 1/V); identical pinout, temp range, and supply specs | Optimized for mid-range applications (10W–40W) balancing resolution and headroom | Choose for simplified calibration where 1.00× scaling aligns directly with mW-per-mV design conventions |
Compared with MAX4210AETT+T and MAX4210BETT+T, the MAX4210CETT+T offers higher gain (1.64 1/V) for improved sensitivity in low-power systems (e.g., <10W battery monitors), trading off some output voltage headroom for finer resolution at low load levels - making it optimal for portable electronics with tight power budgets.

FAQ
What is the exact power gain of MAX4210CETT+T, and how is it implemented?
The MAX4210CETT+T has a fixed power gain of 1.64 1/V, corresponding to the 'C' variant in the MAX4210 series. This gain is implemented via an internal 25:1 resistor-divider network that scales the VRS+ input before multiplication with VSENSE. Unlike variants D/E/F, no external resistors are required - the gain is factory-trimmed and specified with ±1.5% accuracy over temperature.
Does MAX4210CETT+T require external components for basic operation?
No - MAX4210CETT+T requires only a 0.1µF ceramic bypass capacitor from VCC to GND for stable operation. Its integrated 25:1 resistor-divider eliminates external scaling resistors needed by MAX4210D/E/F variants. RS+ and RS− connect directly to the sense resistor terminals, and POUT drives directly into an ADC or comparator without buffering in most designs.
Can MAX4210CETT+T monitor loads powered from 3.3V rails?
No - MAX4210CETT+T requires a minimum +4V common-mode input voltage at RS+, as specified in its absolute maximum ratings and electrical characteristics. It is not rated for 3.3V systems. For lower-voltage rails, consider the MAX4211 series or alternative current-sense amplifiers with extended low-VCM range.
What is the maximum capacitive load MAX4210CETT+T can drive on POUT without oscillation?
MAX4210CETT+T maintains stability with capacitive loads up to 450pF on the POUT pin, as confirmed in the Electrical Characteristics table under "Capacitive-Load Stability (POUT, IOUT, REF)". Loads exceeding this value may cause peaking or sustained oscillation and require isolation or active buffering.
How does MAX4210CETT+T handle overvoltage or overcurrent events?
MAX4210CETT+T itself does not include comparators or fault outputs - those features are exclusive to the MAX4211 series. As a pure analog monitor, MAX4210CETT+T provides only the POUT signal; external circuitry (e.g., comparators, MCUs) must implement overpower/overcurrent detection using this output. Its role is precise, real-time sensing - not autonomous protection.
