IQS213A-00000000-MSR

Overview

The IQS213A-00000000-MSR is a 3-channel capacitive touch and swipe function controller from the Azoteq ProxSense series. It operates on a supply voltage of 1.8V to 3.6V with current consumption under 5µA in low power modes. The device features an internal voltage regulator and reference capacitor, supporting both self-capacitance and projected capacitance configurations. It offers configurable swipe or individual touch outputs via GPIO or I2C interface. The component is housed in a small outline MSOP-10 package and supports One Time Programmable (OTP) options for hardware configuration.

Feature Summary

• Supports variable swipe function configurations alongside standard touch sensing capabilities
• Includes Automatic Tuning Implementation (ATI) for optimal sensitivity across varying environments
• Features internal voltage regulation and on-chip reference capacitor for minimal external components
• Provides flexible output modes including standalone GPIO and programmable I2C communication

Applications

• Sanitary ware and office equipment controls
• Flashlights, headlamps, and keychain lights
• Splash-proof or waterproof devices requiring high immunity to aqueous substances
• Swipe-to-unlock or wake-from-standby interfaces
• Replacement for traditional electro-mechanical switches

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout and packaging details. Confirm that the OTP settings match the intended application requirements, as default configurations may differ from programmed states. Ensure compatibility with the target supply voltage range and interface protocol before integration.

Selection Notes

Select this model for applications requiring high sensitivity and robust noise immunity against environmental factors. Consider the MSOP-10 package constraints for PCB layout. Evaluate whether the 3-channel capacity meets the electrode count needs. Verify if the I2C interface is required or if standalone GPIO operation suffices for the design.

Part Context

This component belongs to the IQS213A family within the Azoteq ProxSense series. It is designed as a fully integrated solution for capacitive sensing, replacing mechanical switches. The 'MSR' suffix typically indicates tape and reel packaging suitable for automated assembly processes.

Replacement Considerations

Check for updated revisions of the IQS213A series. Consult the manufacturer for any end-of-life notifications or recommended successor models. Ensure pin compatibility if substituting with other members of the IQS213 family.
