High-side current monitor for 4V to 28V rails
The MAX4211BEUE+ is a high-side current monitor from Analog Devices (formerly Maxim Integrated) that measures load current by sensing the voltage drop across an external sense resistor placed between the supply rail and the load. It outputs a voltage proportional to that current, making it a direct feed for an ADC or comparator. The ±0.5% accuracy holds across the full 4V to 28V input range and the -40°C to 85°C industrial temperature band, so the measurement stays tight whether the rail is a 5V logic supply or a 24V motor bus.
What the ±0.5% accuracy means for the BOM
The ±0.5% accuracy holds across the 4V to 28V input range.
