IS31SE5100-QFLS2-TR

Overview

The IS31SE5100-QFLS2-TR is a capacitive touch sensor IC from Lumissil Microsystems, designed for multi-button applications. It features an 8-channel configuration housed in a compact 24-WFQFN Exposed Pad package. The device supports standard I2C communication interfaces for system integration. It operates within a supply voltage range of 2.7V to 5.5V and is rated for industrial temperature ranges, ensuring reliable performance in various electronic environments.

Feature Summary

Supports 8 independent capacitive touch channels for button detection
Integrated I2C interface for efficient data transmission and control
Compact 24-pin QFN package design suitable for space-constrained PCB layouts

Applications

Consumer electronics touch interfaces
Industrial control panel buttons
Appliance user interface inputs

Procurement Notes

Verify the specific suffix -TR indicates tape and reel packaging when sourcing components. Confirm that the 24-WFQFN Exposed Pad footprint matches your PCB design requirements. Ensure compatibility with the required I2C bus speed and voltage levels for your target application environment before finalizing procurement.

Selection Notes

Select this component for designs requiring multiple discrete touch inputs without complex gesture processing. The 8-channel capacity fits standard remote or appliance control panels. Consider the exposed pad thermal management needs during layout. This part serves as a direct replacement for legacy capacitive touch controllers in similar channel count configurations.

Part Context

This model belongs to the IS31SE series of capacitive touch sensors manufactured by Lumissil Microsystems. It complements other interface and sensor solutions in their portfolio, focusing on low-cost, high-reliability touch detection. The series targets mass-market electronics where simple button interaction is required over complex touchscreens.
