Product details

What this current-sense amp does on your board

The MAX4173HESA+ is a single-channel current-sense amplifier. The 1.2 MHz bandwidth tracks load transients. Supply span runs from 3 V to 28 V. Input offset is 300 µV. Quiescent draw is 420 µA.

Temperature grade and environment

Rated for -40°C to 85°C, so it handles outdoor telecom cabinets, factory-floor enclosures, and under-hood automotive auxiliary circuits that don't see direct engine-block heat. The 8-SOIC package is a standard footprint for industrial control PCBs — no special reflow profile, no fine-pitch inspection needed.

Sourcing and lifecycle

Lifecycle status is Active per the manufacturer, and the part carries ROHS3 compliance. No LTB notice or successor code has been issued — this is a current-production line. Sourced through independent distribution; availability and current pricing confirmed at RFQ time against your BOM line.

Frequently asked questions

Can MAX4173HESA+ be used for high-side current sensing?

Yes — it is a current-sense amplifier, and the wide common-mode range (implied by the 28 V supply max) supports high-side sensing on rails up to 28 V.
