IS31SE5100-SALS2

Overview

The IS31SE5100-SALS2 is a capacitive touch sensor IC designed for button applications, manufactured by Lumissil Microsystems. It features an 8-channel input configuration and integrates 8 LED driver channels for user interface feedback. The device operates within a supply voltage range of 2.7V to 5.5V and draws approximately 175µA of typical supply current, supporting low-power designs. It is housed in a 24-SSOP package with a bare pad for thermal management. The component supports I2C communication and functions across an operating temperature range of -40°C to 85°C.

Feature Summary

Integrates eight capacitive touch sensing channels for multi-button detection
Includes eight dedicated LED driver channels for status indication
Supports low-power operation with typical supply current of 175µA
Utilizes I2C interface for system communication

Applications

Consumer electronics control panels
Appliance user interfaces
Industrial equipment touch buttons
Automotive interior controls

Procurement Notes

Verify the specific suffix SALS2 against the manufacturer's latest documentation to confirm package type and pinout compatibility. Confirm that the 24-SSOP footprint matches the target PCB design. Check for any recent lifecycle notices or obsolescence warnings from Lumissil Microsystems prior to finalizing procurement plans.

Selection Notes

Select this component when an integrated solution for both touch sensing and LED driving is required to reduce bill of materials count. Ensure the application environment stays within the specified -40°C to 85°C temperature range. Verify that the I2C bus speed and address configuration align with the host microcontroller capabilities.

Part Context

This part belongs to the IS31SE5100 series of capacitive touch sensors from Lumissil Microsystems. It is distinct from development tools like the IS31SE5100-QFLS2-EB and other variants such as the IS31SE5118A. The SALS2 designation specifically identifies the 24-SSOP packaged version intended for surface-mount assembly in compact electronic devices.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Designers should consult Lumissil Microsystems directly for recommended alternatives or cross-reference options if this component is no longer suitable for the design.
