Overview
The LDS6107NQGI8 is a capacitive touch sensor controller from the PureTouch family, manufactured by Renesas Electronics. It features 13 sensor channels and supports buttons, sliders, and scroll wheels. The device operates on a 1.65V to 5.5V supply with current consumption under 125µA in full power and under 50µA in low power modes. It offers I2C, SPI, and SMBus interfaces with VDDIO. Five pins can be configured as Direct Communication Mode outputs. It is housed in a 28-pin VFQFPN package.
Feature Summary
- Supports multiple input types including buttons, sliders, and scroll wheels
- Configurable hysteresis and debounce settings for signal stability
- Includes five optional Direct Communication Mode outputs
Applications
- Capacitive touch sensor applications requiring high accuracy
- Interfaces supporting slider and scroll wheel inputs
- Systems utilizing I2C, SPI, or SMBus communication protocols
Procurement Notes
Verify component status before integration as this part is listed as obsolete. Confirm availability through authorized distributors or secondary markets. Check for End-of-Life notifications and Product Change Notices regarding assembly locations or packaging updates. Ensure compatibility with existing design specifications if substituting.
Selection Notes
Select this controller for designs requiring up to 13 capacitive sensing channels. Consider the 28-pin VFQFPN package constraints during PCB layout. Evaluate power requirements against the specified full power and low power consumption levels. Verify interface compatibility with the host microcontroller using I2C, SPI, or SMBus options.
Part Context
This component belongs to the IDT/LDS PureTouch family of capacitive touch controllers. It shares functional similarities with other members like the LDS6107PYGI8 but differs in package type. The series is designed for accurate touch detection across various input modalities.
Replacement Considerations
The LDS6107NQGI8 is marked as obsolete. Potential alternatives within the same family include the LDS6107PYGI8, which utilizes a 28-SSOP package instead of VFQFPN. Verify pinout and package dimensions when considering substitutes.
