IS31SE5118-ZNLS3-TR

Overview

The IS31SE5118-ZNLS3-TR is a capacitive touch sensor IC manufactured by Lumissil Microsystems. It features an 8-channel programmable capacitive touch interface housed in a 16-TSSOP package with dimensions of 0.173 inches width (4.40mm). The device operates on a supply voltage range of 2.7V to 5.5V and utilizes an I2C interface for communication. Designed for surface mount technology, it supports applications requiring shared GPIO input capabilities within a compact form factor.

Feature Summary

Supports 8-channel programmable capacitive touch sensing
Utilizes I2C interface for system communication
Enables capacitive touch input through shared GPIO

Applications

Consumer electronics touch interfaces
Industrial control panels
IoT device input modules

Procurement Notes

Verify the specific package variant against design requirements, as datasheets may list multiple options like QFN or TSSOP. Confirm operating temperature ranges and supply voltage specifications match the target application environment. Ensure ESD protection measures are adequate for the chosen interface. Cross-reference the manufacturer part number with official Lumissil documentation to confirm current production status and availability constraints.

Selection Notes

Select this component when an 8-channel capacitive touch solution is required in a 16-pin TSSOP footprint. Compare against other channel counts if more inputs are needed. Consider the I2C interface compatibility with the host microcontroller. Evaluate the 2.7V to 5.5V supply range against the system power architecture. Check mechanical constraints regarding the 4.40mm width package size.

Part Context

This part belongs to the Lumissil IS31SE series of capacitive touch sensors. It shares functional similarities with other models in the family, such as the IS31SE5117B, which offers 16 channels. The ZNLS3 suffix indicates the specific TSSOP packaging option. It serves as a dedicated controller for detecting user touch inputs via capacitance changes.

Replacement Considerations

The IS31SE5118A-QFLS3-TR is a related model offering 8 channels but in a QFN-16 package. The IS31SE5117B-QFLS3-TR provides 16 channels in a QFN-24 package. Verify pinout compatibility and package dimensions before substituting.
