QT113H-IS

Overview

The QT113H-IS is a single-channel capacitive touch and proximity sensor integrated circuit manufactured by Microchip Technology. It belongs to the QProx series and is designed for button-style input detection. The device operates within a supply voltage range of 2.5V to 5.5V and draws a supply current of 600µA. It features a 14-bit resolution for sensing accuracy. The component is housed in an 8-SOIC package with a width of 3.90mm and supports surface mount installation. It functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Capacitive sensing technology for touch and proximity detection
• Single-channel configuration optimized for button applications
• Integrated 14-bit resolution for precise signal processing

Applications

• Capacitive touch button interfaces
• Proximity detection systems
• Consumer electronics control panels

Procurement Notes

Verify component status as the QT113H-IS is listed as obsolete or end-of-life. Confirm availability through authorized distributors or secondary market sources. Check for RoHS compliance status, which may differ from current standards. Ensure the 8-SOIC package dimensions match the target PCB footprint before procurement.

Selection Notes

Select this component for designs requiring a dedicated single-channel capacitive touch solution. Verify that the 2.5V to 5.5V supply voltage aligns with the system power rails. Consider the 600µA supply current for battery-operated applications. Ensure the design accommodates the 8-SOIC package size and the specified operating temperature range.

Part Context

The QT113H-IS is part of Microchip's QProx family of capacitive sensing products. This series focuses on providing reliable touch and proximity detection capabilities. The specific model targets simple interface requirements with a single sensing channel. It serves as a specialized sensor IC rather than a general-purpose microcontroller.

Replacement Considerations

As the QT113H-IS is marked as obsolete, identify alternative single-channel capacitive touch sensors from Microchip or other manufacturers. Verify pin compatibility and functional equivalence for direct replacement. Review datasheets for updated packages and compliance certifications.
