Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet revision to ensure correct package type and configuration. Confirm that the component meets RoHS and Reach compliance requirements for your target market. Check for any recent product discontinuance notifications or part number revisions before finalizing procurement plans.

Selection Notes

Select this component when a design requires simultaneous support for capacitive touch, magnetic field detection, and inductive sensing without increasing board space. Ensure the application environment stays within the specified -20°C to +85°C operating temperature range. Verify that the system power supply can maintain the required voltage levels during peak sensor activation currents.

Part Context

This part belongs to the IQS620A family within the ProxFusion series, designed to consolidate multiple sensing modalities into a single chip. It replaces discrete sensor solutions by providing a unified platform for capacitive, Hall-effect, and inductive inputs. The DNR suffix indicates the DFN(3x3)-10 package variant, which offers a low-profile form factor suitable for space-constrained portable electronics.

Replacement Considerations

Check for updated datasheet revisions that may have superseded this part number. Verify if newer generation sensors offer improved power efficiency or additional channel counts. Ensure any substitute maintains compatibility with existing I2C communication protocols and GPIO configurations.
