Overview
The AT42QT1012-TSHR is a single-channel capacitive touch sensor IC from Microchip Technology's QTouch series. It features a toggle output with programmable auto switch-off capability. The device operates on a supply voltage of 1.8V to 5.5V and draws 378.5µA. It utilizes a digital active high/low interface and offers 14-bit resolution. The component is housed in a SOT-23-6 surface-mount package and functions within a temperature range of -40°C to 85°C.
Feature Summary
- Provides a touch on/touch off toggle output state for button applications.
- Includes programmable auto switch-off functionality to manage power states.
- Supports proximity detection capabilities alongside standard touch sensing.
Applications
- Capacitive touch button interfaces
- Proximity sensing systems
- Low-power consumer electronics
Procurement Notes
Verify the specific suffix TSHR confirms the SOT-23-6 reel packaging format. Ensure compatibility with the required operating voltage range of 1.8V to 5.5V. Confirm that the digital active high/low interface aligns with the target microcontroller logic levels. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.
Selection Notes
Select this component when a single-button capacitive solution with toggle behavior is required. The integrated auto switch-off feature simplifies power management compared to devices lacking this function. The SOT-23-6 package suits space-constrained designs where minimal footprint is critical. Consider the 14-bit resolution for sensitivity requirements in small electrode designs.
Part Context
This part belongs to the AT42QT101x family of single-channel QTouch sensors. It shares core architecture with the AT42QT1010 but differs in output control logic, specifically offering toggle functionality rather than momentary output. This distinction makes it suitable for latching applications without external software handling.
Replacement Considerations
The AT42QT1010-TSHR serves as a functional substitute if momentary output behavior is acceptable instead of toggle. Verify pinout compatibility between the SOT-23-6 variants before substitution. Software configuration differences regarding output modes must be addressed during integration.
