IQS6210U9R

Overview

The IQS6210U9R is a multifunctional sensor IC from the Azoteq ProxFusion series, integrating ambient light sensing (ALS), capacitive proximity/touch, Hall-effect, and inductive sensing capabilities. It operates on a supply voltage of 1.8V to 3.3V with low power consumption ranging from 2.5µA to 95µA depending on the active channel and response rate. The device features Automatic Tuning Implementation (ATI) for stability against environmental changes and communicates via a standard I2C interface. It is housed in a compact UOLG-2.8 x 2.5 x 0.6–9-pin package suitable for space-constrained applications.

Feature Summary

• Combines capacitive, Hall-effect, inductive, and ambient light sensing technologies in a single platform.
• Features Automatic Tuning Implementation (ATI) for enhanced temperature stability and sensitivity compensation.
• Supports multiple user interface options including proximity wake-up, touch, and hysteresis modes.
• Provides absolute lux output for ALS with human eye response compensation.

Applications

• Mobile electronics such as smartphones and tablets
• Home automation and lighting control systems
• White goods and household appliances
• Wearable devices requiring multi-modal sensing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct package type and temperature range. Confirm RoHS compliance status and check for any recent product discontinuance notifications or alternative part number recommendations from Azoteq before finalizing procurement.

Selection Notes

Select this component when an application requires simultaneous or selectable operation of capacitive, magnetic, and optical sensors within a minimal footprint. Ensure the design supports the required I2C communication speed and that the external coil for inductive sensing meets the impedance requirements specified in the reference schematic.

Part Context

The IQS6210U9R belongs to the IQ Switch ProxFusion series, which merges ProxSense capacitive technology with additional sensor types. This integration allows designers to replace multiple discrete sensors with a single controller, reducing bill of materials and board space while maintaining ultra-low power performance across various activation modes.

Replacement Considerations

Check for updated revision numbers or suffixes in the latest Azoteq documentation. No direct public substitute part numbers are confirmed; verify compatibility with existing firmware if migrating from earlier IQS62x variants.
