Touch Capacitive Sensor Procurement Notes

This component is classified as an End-of-Life (EOL) product by the manufacturer. Distribution availability is restricted, and current stock levels may be limited or unavailable through standard channels. Engineers should verify specific lot availability and lead times directly with authorized distributors before initiating procurement processes.

Touch Capacitive Sensor Selection Notes

Designers requiring active production status should evaluate alternative components within the same family or newer generations from Semtech. Verify that the MLPQ-UT28 package footprint matches existing PCB layouts. Ensure the I2C address configuration aligns with system bus requirements and that the operating voltage range is compatible with the target power supply rails.

Touch Capacitive Sensor Part Context

The SX8636 series belongs to Semtech's portfolio of analog mixed-signal integrated circuits focused on user interface solutions. These devices are engineered to provide reliable touch sensing functionality for modern electronic systems. The specific model integrates necessary signal processing capabilities to detect capacitance changes accurately.

Touch Capacitive Sensor Replacement Considerations
