High-side current monitor in a SOT-23-6
The Maxim Integrated MAX4004EUT is a high-side current monitor designed to sense current on the supply rail without disturbing the ground path. It operates over a 2.7V to 22V input range, making it suited for monitoring loads in industrial control, telecom, and automotive auxiliary circuits where the supply is above the logic rail. The ±5% accuracy covers the typical needs of overcurrent detection and load monitoring where a precision measurement IC would be overkill. Packaged in a SOT-23-6, it fits into tight layouts and is a common footprint for replacement on a repair bench.
Package and mounting
The ±5% accuracy holds across the -40°C to 85°C temperature range.
Sourcing and lifecycle — still an active line
The part is RoHS non-compliant per the listing, which matters if your BOM requires full RoHS exemption or if you are working to a specific environmental compliance directive. For a repair bench, this means you can still order fresh date-code parts rather than relying on pulled or surplus stock.
