Overview
The QT113-S is a charge-transfer touch sensor IC from Microchip Technology's QTouch family. It detects near-proximity or touch through air and dielectrics such as glass, plastic, stone, ceramic, and wood. The device operates on a single supply voltage of 2.5V to 5V with a typical current consumption of 600µA. It features continuous autocalibration, eliminating the need for manual adjustments. The output is active-low, providing a HeartBeat health indicator. Only one external capacitor is required for operation.
Feature Summary
- Projects a proximity sense field through air and various dielectric materials
- Continuous 100% autocalibration for life without manual adjustment
- Single-supply operation at 2.5V to 5V with 600µA current consumption
- Active-low output with HeartBeat health indicator
Applications
- Elevator buttons
- Toys and games
- Access systems
- Appliance control
- Light switches
Procurement Notes
Verify the specific suffix 'S' against the manufacturer datasheet to confirm pinout and electrical characteristics. Confirm RoHS compliance status as historical data may vary by production batch. Check for end-of-life notifications or obsolescence warnings before finalizing procurement plans.
Selection Notes
Select the QT113-S when an active-low output signal is required. Compare with the QT113H variant if an active-high output is necessary for system logic compatibility. Ensure the application environment allows for the required external capacitor value to set sensitivity levels appropriately.
Part Context
The QT113-S belongs to the Quantum Research Group (now Microchip) QTouch series of charge-transfer sensors. It is designed to replace mechanical switches in applications requiring low-cost, reliable touch detection through non-conductive surfaces.
