IS31SE5120A-QFLS3-TR

Overview

The IS31SE5120A-QFLS3-TR is a capacitive touch sensor controller manufactured by Lumissil Microsystems. It features up to 24 input channels and supports active proximity detection. The device operates on an I2C interface and functions within a supply voltage range of 2.3V to 5.5V. It draws a maximum supply current of 150µA and supports an operating temperature range from -40°C to +105°C. The component is housed in a 32-WFQFN package with dimensions of 5mm x 5mm, utilizing surface mount technology.

Feature Summary

Capacitive touch sensing with integrated active proximity detection capabilities
Supports up to 24 input channels for scalable button configurations
I2C communication interface for system integration

Applications

Capacitive touch button interfaces
Proximity sensing applications
Consumer electronics control panels

Procurement Notes

Verify the specific suffix QFLS3 against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the required I2C bus speed and check moisture sensitivity level (MSL 3) requirements during storage and handling procedures before assembly.

Selection Notes

Select this component when a solution supporting up to 24 channels with proximity functionality is required. Verify that the 32-WFQFN footprint fits the PCB layout constraints. Confirm that the 2.3V to 5.5V supply range aligns with the target system power architecture and that the -40°C to +105°C temperature rating meets environmental demands.

Part Context

This part belongs to the IS31SE series of capacitive touch controllers from Lumissil Microsystems. It is designed for applications requiring multiple touch inputs and proximity detection within a compact form factor. The series utilizes standard I2C communication for easy integration with microcontrollers.

Replacement Considerations

Check Lumissil datasheets for other members of the IS31SE family with compatible pinouts or software registers. Verify if alternative suppliers offer functionally equivalent capacitive touch controllers with similar channel counts and proximity features.
