High-side current monitor for 4V to 28V rails
The Analog Devices MAX4211FETE+C3C is a high-side current monitor that measures current on the supply rail without disturbing the ground path. Its ±0.5% accuracy makes it a fit for precision power monitoring in industrial control, telecom infrastructure, and battery-powered equipment where you need to track load current without adding a ground offset. The input voltage range spans 4V to 28V, covering common 5V, 12V, and 24V rails used across factory automation, base stations, and test equipment. Operating temperature from -40°C to 85°C suits it for outdoor cabinets and unconditioned factory floors.
Lifecycle and sourcing
No second-source or pin-compatible alternate is listed in the available records; for dual-sourcing resilience, a review of the broader family may identify a functional equivalent, but no direct pin-compatible drop-in is confirmed here.
