Product details
Overview
MAX4210BETT+T from Maxim Integrated is a high-side power and current monitor IC with integrated 25:1 resistor-divider, 25.00V/V current-sense gain, ±1.5% max current-sense accuracy, ±1.5% max power-sense accuracy, and 220kHz bandwidth. It operates from +2.7V to +5.5V supply and measures load current and source voltage (4V to 28V) in battery-powered systems without disrupting the ground path.
For engineers reviewing the MAX4210BETT+T datasheet, MAX4210BETT+T pinout, MAX4210BETT+T application, or MAX4210BETT+T equivalent, this device supports real-time analog power monitoring in space-constrained designs requiring stable output for overpower detection, smart battery management, and short-circuit protection circuits.
Technical Context
The MAX4210BETT+T implements a high-side current-sense amplifier that multiplies sensed current (via external shunt) and source voltage to generate an analog POUT proportional to instantaneous power. Its internal 25:1 resistor-divider eliminates external components for VIN scaling in MAX4210A/B/C variants.
It features fixed 25.00V/V current-sense gain and 1.00 1/V power-sense gain, enabling direct output voltage interpretation as mW when VSENSE is referenced to 100mV full-scale and VRS+ is known. The device delivers 380µA typical supply current and maintains ±1.5% accuracy across –40°C to +85°C.

FAQ
What is the function of the N.C. pin on MAX4210BETT+T?
The N.C. (No Connection) pin on MAX4210BETT+T - Pin 2 in the 6-pin TDFN package - has no internal connection and must be left unconnected on the PCB. It is not tied to any internal node and does not require grounding or routing, simplifying layout in dense board designs.
Does MAX4210BETT+T require external resistors for voltage scaling?
No. MAX4210BETT+T integrates a 25:1 resistor-divider network internally, eliminating the need for external resistors to scale the RS+ voltage for power computation. This distinguishes it from MAX4210D/E/F variants and reduces component count and layout area.
What is the maximum common-mode voltage supported at RS+ for MAX4210BETT+T?
MAX4210BETT+T supports a +4V to +28V common-mode input range at the RS+ pin. This allows direct high-side sensing in 12V and 24V systems without level-shifting circuitry, maintaining accuracy and isolation from the load ground path.
How accurate is the power output (POUT) of MAX4210BETT+T over temperature?
MAX4210BETT+T guarantees ±1.5% total POUT output error over the full –40°C to +85°C operating range. This includes combined effects of gain error, offset, and multiplier nonlinearity, ensuring consistent power reporting in automotive and industrial environments.
Can MAX4210BETT+T be used with a 3.3V supply?
Yes. MAX4210BETT+T operates from +2.7V to +5.5V, making it fully compatible with 3.3V logic and supply rails. At VCC = 3.3V, it maintains specified accuracy, bandwidth, and output drive capability - confirmed in electrical characteristics tables across supply voltage conditions.
