Analog Devices Inc./Maxim Integrated MAX4210EETT+

Overview

MAX4210EETT+ from Maxim Integrated is a high-side power/current monitor IC that delivers an analog voltage output proportional to load power (V_SENSE × V_RS+) with 25.00 V/V current-sense gain and 25.00 1/V power-sense gain. It operates from +2.7V to +5.5V supply, supports +4V to +28V input common-mode range, achieves ±1.5% max current- and power-sense accuracy, and targets battery-powered systems where ground-path integrity is critical.

For engineers reviewing the MAX4210EETT+ datasheet, MAX4210EETT+ pinout, MAX4210EETT+ application, or MAX4210EETT+ equivalent, this device serves as a precision, low-power, 6-pin TDFN solution for real-time high-side power monitoring in smart battery packs, overload protection circuits, and power-supply displays-where compact size, wide input voltage tolerance, and guaranteed accuracy across -40°C to +85°C are essential.

Technical Context

The MAX4210EETT+ implements a dedicated analog multiplier architecture that multiplies sensed current (via high-side shunt) with source voltage to generate a true power-proportional output (POUT). Its internal 25:1 resistor-divider network eliminates external components required by D/E/F variants, simplifying design for fixed-gain applications.

This variant uses the MAX4210E configuration: it features 25.00 V/V current-sense gain and 25.00 1/V power-sense gain, supports 100mV full-scale sense voltage, and delivers 220kHz bandwidth on both IOUT and POUT outputs-enabling fast response to transient overloads without phase reversal under overdrive conditions.

FAQ

What is the primary function of the MAX4210EETT+?

The MAX4210EETT+ is a high-side power and current monitor IC that outputs analog voltages proportional to load current (IOUT) and load power (POUT). Specifically, it multiplies the voltage across a high-side sense resistor (V_SENSE) with the source voltage (V_RS+ or scaled VIN) to deliver real-time, calibrated power data-enabling accurate energy monitoring without disrupting the load's ground path. Its 25.00 V/V and 25.00 1/V gains make the MAX4210EETT+ ideal for mid-range current applications.

Does the MAX4210EETT+ require external resistors for VIN scaling?

No. The MAX4210EETT+ integrates a precise 25:1 resistor-divider network internally, eliminating the need for external scaling resistors on the VIN input. This distinguishes it from MAX4210D/E/F variants and reduces component count, PCB area, and potential calibration drift-making the MAX4210EETT+ a drop-in solution for applications requiring fixed 25.00 1/V power gain and simplified layout.

What is the operating temperature range for the MAX4210EETT+?

The MAX4210EETT+ is fully specified for operation from -40°C to +85°C ambient temperature. All key parameters-including ±1.5% current- and power-sense accuracy, 220kHz bandwidth, and supply current-are guaranteed across this extended industrial temperature range. This makes the MAX4210EETT+ suitable for deployment in automotive cabin modules, industrial controllers, and outdoor power equipment where thermal resilience is mandatory.

Can the MAX4210EETT+ be used in 12V or 24V automotive systems?

Yes. The MAX4210EETT+ supports a +4V to +28V input common-mode voltage range on its RS+ pin, enabling direct high-side sensing on 12V and 24V automotive power rails without level shifters or isolation. Its 380µA supply current and -40°C to +85°C rating further align with automotive body electronics requirements-making the MAX4210EETT+ applicable in battery disconnect units, junction box monitors, and ADAS power supervisors.

How does the MAX4210EETT+ differ from the MAX4211 series?

The MAX4210EETT+ is a simplified, 6-pin power monitor without comparators or reference outputs, whereas the MAX4211 includes two open-drain comparators, a 1.21V bandgap reference, and additional control pins (LE, INHIBIT, CIN1/CIN2). The MAX4210EETT+ prioritizes minimal footprint and low cost for pure analog monitoring, while the MAX4211 targets full-featured circuit-breaker and fault-detection applications. They share identical gain options and accuracy specs-but only the MAX4210EETT+ uses the compact TDFN-6 package.
