CG8179AA

Overview

The CG8179AA is an automotive-qualified capacitive touch controller manufactured by Infineon Technologies. It features a 16-pin SOIC package and supports up to 10 CapSense I/O pins and 5 general-purpose outputs. The device operates within a voltage range of 1.71 V to 5.50 V and functions reliably between -40°C and +85°C. Key capabilities include proximity sensing, SmartSense technology for automatic tuning, and communication via I2C and GPO interfaces.

Feature Summary

• Integrated SmartSense technology enables automatic tuning and calibration for stable performance across varying environmental conditions.
• Supports proximity sensing functionality to detect approaching objects before physical contact occurs.
• Designed specifically for automotive applications with qualification standards ensuring reliability in demanding environments.

Applications

• Automotive infotainment systems requiring capacitive slider or button inputs
• Vehicle control panels utilizing proximity detection for enhanced user interaction
• Embedded human-machine interface (HMI) modules in automotive electronics

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm exact package type and temperature grade. Confirm RoHS compliance status and lead times directly with authorized distributors prior to procurement. Ensure the selected variant matches the required automotive qualification standards for your specific application environment.

Selection Notes

Select this component when an automotive-grade capacitive touch solution with integrated SmartSense tuning is required. Verify that the 16-pin SOIC package fits the board layout constraints. Ensure the system design accommodates the 1.71 V to 5.50 V operating voltage range and utilizes I2C or GPO for communication.

Part Context

This part belongs to the Cypress/Infineon family of capacitive touch controllers designed for embedded applications. It integrates sensing logic and processing capabilities into a single chip, reducing external component count compared to discrete solutions. The automotive qualification distinguishes it from standard commercial-grade counterparts.

Replacement Considerations

Check for updated part numbers within the same Infineon portfolio as older Cypress designs may have successors. Verify pin-to-pin compatibility if substituting with other 16-pin SOIC touch controllers. Ensure functional equivalence regarding SmartSense and proximity sensing requirements.
