Analog Devices Inc./Maxim Integrated MAX4210BETT-T

Overview

MAX4210BETT-T from Maxim Integrated is a high-side power and current monitor IC with integrated 25:1 resistor-divider, delivering analog POUT voltage proportional to load power (V_SENSE × V_RS+). It features 25.00 V/V current-sense gain, ±1.5% max power-sense accuracy, 220kHz bandwidth, and operates from +4V to +28V input source voltage - ideal for smart battery pack monitoring and overpower circuit-breaker protection in space-constrained portable systems.

For engineers reviewing the MAX4210BETT-T datasheet, MAX4210BETT-T pinout, MAX4210BETT-T application, or MAX4210BETT-T equivalent, this device offers verified real-time power monitoring with low 380µA supply current, fixed internal gain configuration, and TDFN-6-EP package compatibility for high-density PCB layouts in battery-powered industrial and consumer electronics.

Technical Context

The MAX4210BETT-T implements a precision analog multiplier architecture that multiplies high-side sensed current (via V_SENSE across external shunt) with the load supply voltage (V_RS+) to generate a proportional power output (POUT). Its internal 25:1 resistor-divider eliminates external components while maintaining full-scale V_SENSE of 150mV and supporting up to 28V common-mode input range.

This variant belongs to the MAX4210A/B/C series with fixed gain options - MAX4210B uses 25.00 V/V current gain and 1.00 1/V power gain - and shares the -40°C to +85°C operating temperature range, 220kHz small-signal bandwidth, and 1.5% max total POUT output error across its specified input conditions.

FAQ

What is the function of the POUT pin on the MAX4210BETT-T?

The POUT pin on the MAX4210BETT-T delivers an analog voltage output proportional to the instantaneous power consumed by the load, calculated as V_SENSE × V_RS+ scaled by the device's fixed 1.00 1/V power gain. This output is ratiometric to V_RS+, enabling direct interface with ADCs or comparators for real-time power analysis without digital computation. The MAX4210BETT-T guarantees ±1.5% max power-sense accuracy over its full operating range.

Does the MAX4210BETT-T require external resistors for gain setting?

No, the MAX4210BETT-T integrates a precision 25:1 resistor-divider network internally, eliminating the need for external gain-setting resistors. This simplifies design, reduces board area, and improves temperature tracking versus discrete resistor solutions. The MAX4210BETT-T is part of the A/B/C variant family defined by fixed internal gain - 25.00 V/V current gain and 1.00 1/V power gain - with no user-adjustable configuration pins or external components required.

What is the maximum common-mode voltage supported by the MAX4210BETT-T?

The MAX4210BETT-T supports a +4V to +28V common-mode input voltage range at the RS+ pin, enabling high-side sensing in 12V and 24V industrial, automotive, and telecom power systems. This specification is validated across the full -40°C to +85°C operating temperature range and does not require level-shifting circuitry. The MAX4210BETT-T maintains ±1.5% power-sense accuracy even at the upper limit of 28V common-mode voltage.

How does the MAX4210BETT-T achieve low power consumption?

The MAX4210BETT-T achieves low power consumption through optimized analog circuit design, drawing only 380µA typical supply current from its +2.7V to +5.5V VCC rail. This quiescent current remains stable across temperature and input conditions, making it suitable for always-on battery monitoring. The MAX4210BETT-T's internal architecture avoids digital blocks or clocked circuits, contributing to its ultra-low static power profile while retaining 220kHz bandwidth and ±1.5% accuracy.

Can the MAX4210BETT-T be used with a 3.3V microcontroller ADC?

Yes, the MAX4210BETT-T's POUT output is fully compatible with 3.3V microcontroller ADCs. Its output voltage swing ranges from ~1.5mV to (VCC – 0.25V), and with VCC = 3.3V, POUT delivers up to 3.05V - well within the 0–3.3V input range of most 3.3V ADCs. The MAX4210BETT-T also features low output impedance (<0.5Ω) and 450pF capacitive-load stability, ensuring clean signal acquisition without external buffering or filtering in typical embedded implementations.
