IQS263-0-MSR

Overview

The IQS263-0-MSR is a 3-channel capacitive touch and proximity controller from the ProxSense series. It supports self or projected capacitance modes with an 8-bit resolution slider or scroll wheel configuration. The device operates on a supply voltage of 1.8V to 3.6V within a temperature range of -20°C to +85°C. It features an I2C interface, automatic tuning implementation (ATI), and movement detection algorithms. Available in MSOP-10 and DFN10 packages, it includes SAR compliance for mobile devices.

Feature Summary

• Configurable 8-bit coordinate calculations for sliders or scroll wheels
• Automatic drift compensation and sensitivity adjustment via ATI
• Integrated movement detection algorithm for anti-theft applications
• SAR compliance for USB dongle-type and mobile devices

Applications

• Volume control and lid closure detection for laptops
• MP3 players and portable electronics
• Wearable electronics
• Movement detection devices such as anti-theft systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and revision level. Confirm availability status as distribution channels may vary. Ensure the component meets RoHS2 compliance requirements for your target market regulations before finalizing procurement orders.

Selection Notes

Select this controller for applications requiring high sensitivity and long proximity ranges. Consider the MSOP-10 or DFN10 package based on PCB space constraints. Evaluate the need for event mode versus streaming mode communication to optimize system power consumption and host processor load during operation.

Part Context

This component belongs to the Azoteq ProxSense series, designed for low-power capacitive sensing. It integrates internal regulators and reference capacitors to reduce external component count. The series emphasizes best-in-class signal-to-noise ratios and power efficiency suitable for battery-operated consumer electronics.

Replacement Considerations

Check for updated revisions within the IQS263 family. Verify pin compatibility if substituting with other IQ Switch controllers. Ensure firmware support matches the new component's register map and feature set.
