High-side current sense with ±0.5% accuracy
The MAX4211FETE+ is a high-side current monitor from Analog Devices, designed to measure load current by sensing the voltage drop across a sense resistor placed between the power supply and the load. The ±0.5% accuracy means the measured current value stays within half a percent of the actual current across the operating range — tight enough for precision power monitoring in systems where a 1% error would trip a protection threshold or skew a charge-counting algorithm.
Input range and temperature grade
The device operates from a 4V to 28V input supply, covering common 5V, 12V, and 24V rails found in industrial and telecom equipment.
Package and board fit
Housed in a 16-WQFN Exposed Pad package (4x4 mm, 16-TQFN), the MAX4211FETE+ requires surface-mount assembly with a thermal pad underneath for heat sinking.
Active lifecycle and compliance
The Tube packaging (standard for small-quantity prototyping and low-volume assembly) is the factory-shipped format.
