Analog Devices Inc./Maxim Integrated MAX4210DETT

Overview

MAX4210DETT 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+) via internal analog multiplication. It features 25.00 V/V current-sense gain, 100 mV full-scale sense voltage, +4V to +28V common-mode input range, and operates from +2.7V to +5.5V supply. Used in smart battery chargers and overpower circuit breakers where ground-path integrity is critical.

For engineers reviewing the MAX4210DETT datasheet, MAX4210DETT pinout, MAX4210DETT application, or MAX4210DETT equivalent, this page provides verified technical context, package-validated pin functions, real-world application cards, and two confirmed alternative parts with documented functional and application-level differences - all specific to the MAX4210DETT variant.

Technical Context

The MAX4210DETT implements a precision analog multiplier architecture combining a high-side current-sense amplifier with an external resistor-divider network for flexible gain configuration. Its POUT output directly encodes power as V_POUT = G_P × V_SENSE × V_IN, where G_P = 25.00 1/V for the 'D' variant. Input stage supports up to +28V common-mode voltage while rejecting supply and common-mode noise with ≥60 dB CMRR and ≥52 dB PSRR.

Designed for low-power, space-constrained systems, it draws only 380 µA typical supply current and achieves 220 kHz bandwidth on both IOUT and POUT paths. The device uses a 6-pin TDFN-6-EP (3mm × 3mm) package with exposed paddle for thermal performance, and operates across –40°C to +85°C without requiring ground-path interruption.

FAQ

What is the function of the POUT pin on the MAX4210DETT?

The POUT pin on the MAX4210DETT outputs an analog voltage proportional to load power: V_POUT = 25.00 × V_SENSE × V_IN. This signal is generated by internal analog multiplication and requires an external resistor-divider network (as specified for the 'D' variant) to scale VIN. POUT drives high-impedance loads up to 450 pF and maintains ±1.5% total output error over temperature.

Does the MAX4210DETT require external components to operate?

Yes - the MAX4210DETT requires an external resistor-divider network on the VIN input to set the power gain scaling factor, consistent with its 'D' variant designation. It also needs a 0.1 µF ceramic bypass capacitor from VCC to GND, and a precision current-sense resistor between RS+ and RS−. No external op-amps or ADCs are needed for basic power monitoring functionality.

What is the maximum common-mode voltage supported by the MAX4210DETT?

The MAX4210DETT supports a common-mode input voltage range of +4V to +28V on the RS+ and RS− pins. This allows direct connection to high-side points in 12V, 24V, and 28V automotive or industrial DC systems without level-shifting circuitry. The specification is guaranteed by output voltage error testing and applies across the full –40°C to +85°C operating range.

How does the MAX4210DETT differ from the MAX4211 series?

The MAX4210DETT is a simplified power monitor with POUT-only output and no comparators or reference output. In contrast, the MAX4211 integrates two open-drain comparators, a 1.21V bandgap reference, and latch-enable logic - making it suitable for autonomous overload detection. The MAX4210DETT prioritizes low cost, low power (380 µA), and minimal footprint over feature richness.

Is the MAX4210DETT pin-compatible with other MAX4210 variants?

Yes - all MAX4210 variants (A/B/C/D/E/F) in the 6-pin TDFN package share identical pinout and footprint, including MAX4210DETT. Differences lie solely in internal gain configuration and whether internal or external resistor dividers are used. This allows drop-in replacement during design iteration or qualification without PCB changes.
