LDS6107NQGI

Overview

The LDS6107NQGI is a capacitive touch sensor controller from the PureTouch family, manufactured by Renesas Electronics. It features 13 sensor input channels and supports buttons, sliders, and scroll wheels. The device operates on a supply voltage of 1.65V to 5.5V with a typical current consumption of 70µA. It offers I2C, SMBus, and SPI serial interfaces. The component is housed in a 28-VFQFPN package and has reached end-of-life status.

Feature Summary

• Supports up to 13 capacitive sensor inputs for various touch interfaces
• Includes Direct Communication Mode (DCM) outputs for mechanical button emulation
• Provides configurable hysteresis and debounce settings
• Features low power consumption modes

Applications

• Capacitive touch control panels
• Appliance user interfaces
• Consumer electronics input devices

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is limited to existing stock or surplus markets. Verify the specific revision and packaging details carefully when sourcing replacements, as original production has ceased. Ensure compatibility with existing firmware and hardware designs before procurement.

Selection Notes

Select this part for applications requiring multiple touch inputs without complex processing overhead. Consider the 28-pin VFQFPN package constraints during PCB layout. Evaluate the need for DCM outputs if direct hardware signaling is required instead of software polling via the serial interface.

Part Context

The LDS6107 belongs to the IDT/Renesas PureTouch LDS6100/6120 family. It shares architectural similarities with the LDS6107PYGI variant but differs in package type. This series was designed to replace older resistive touch solutions with more durable capacitive alternatives.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, no direct pin-to-pin replacement is explicitly listed. Designers should review the LDS6100 Family datasheet for potential functional equivalents within the same product line.
