Overview
The LDS6203NTGI8 is a capacitive touch controller from the PureTouch family, manufactured by Renesas Electronics Corporation. It supports up to eight input channels for buttons, sliders, and wheels. The device operates on an I2C interface with a supply voltage range of 1.65V to 5.5V and consumes 55µA of current. It features proximity detection capabilities and functions within a temperature range of -40°C to 85°C. The component is housed in a 20-VFQFN package with exposed pad, specifically a 20-TQFN (3x3) footprint, designed for surface mount installation.
Feature Summary
- Capacitive sensing technology supporting multiple input configurations including buttons, sliders, and rotary wheels
- Integrated proximity detection functionality for enhanced user interaction
- Standard I2C communication interface for system integration
Applications
- Consumer electronics requiring capacitive touch interfaces
- Home appliances with control panels
- Industrial equipment with operator interfaces
Procurement Notes
Verify component status as the base part number indicates end-of-life status. Confirm availability through authorized distributors or secondary market sources. Ensure compatibility with existing PCB footprints and firmware drivers. Check for RoHS compliance documentation. Validate package specifications against design requirements before procurement.
Selection Notes
Select this component when a low-power capacitive touch solution with proximity sensing is required. Consider the 20-pin VFQFN package constraints during layout. Verify I2C address configuration needs. Evaluate power consumption requirements against the 55µA specification. Ensure operating voltage matches the 1.65V to 5.5V range.
Part Context
This part belongs to the IDT LDS6200 family of capacitive touch controllers. The series offers integrated solutions for human-machine interfaces. Renesas acquired IDT, continuing support for legacy components. The LDS6203 variant provides specific channel counts and feature sets within the broader product line.
Replacement Considerations
Check for direct pin-to-pin replacements within the LDS6200 family. Verify firmware compatibility if substituting with similar touch controllers. Assess package dimension tolerances for alternative vendors. Confirm electrical parameter equivalence for voltage and current specifications.
