IQS9151-000QFR

Overview

The IQS9151-000QFR is a single-channel capacitance touch sensor IC from the Azoteq ProxFusion series, designed for multi-function trackpad applications. It integrates proximity, touch, snap, and gesture detection capabilities within a QFN-52 package measuring 7.2 mm x 7.2 mm. The device operates on an I2C interface with a supply voltage range of 2.2 V to 3.5 V. It supports button, slider, wheel, and proximity sensing types. The component functions reliably within an operating temperature range of -40°C to +85°C and utilizes SMD/SMT termination for surface mount assembly.

Feature Summary

• Integrates multi-function trackpad functionality including proximity, touch, snap, and gesture detection in a single channel.
• Supports diverse input configurations such as buttons, sliders, wheels, and proximity sensors.
• Communicates via standard I2C interface for system integration.

Applications

• Multi-function trackpads
• Proximity sensing interfaces
• Gesture recognition inputs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct configuration. Confirm RoHS compliance status through official datasheets before procurement. Check humidity sensitivity handling requirements during storage and assembly. Validate that the QFN-52 package dimensions match the target PCB footprint design constraints.

Selection Notes

Select this component when a single-channel solution with integrated proximity and gesture capabilities is required. Ensure the application environment falls within the specified -40°C to +85°C operating temperature range. Verify that the I2C interface is compatible with the host microcontroller. Consider the 7.2 mm x 7.2 mm package size for spatial constraints in the final enclosure design.

Part Context
