Sensor, Capacitive Touch ICs are interface and sensing components used to detect human touch through capacitive sensing technology. They are widely used in touch buttons, sliders, control panels, consumer electronics, home appliances, industrial control interfaces, medical devices, automotive electronics, IoT products and embedded systems.

This category includes capacitive touch sensor ICs, touch controller ICs, touch button controllers, multi-channel touch sensors, proximity sensing ICs and related human-machine interface components. These devices are commonly selected based on channel count, sensitivity, interface type, operating voltage, noise immunity, package type and application requirements.

TomatoElec supplies original Capacitive Touch Sensor ICs from recognized semiconductor manufacturers such as Texas Instruments, Microchip, STMicroelectronics, NXP, onsemi, Renesas, Infineon, Diodes Incorporated and other major brands. As an in-stock electronic components supplier and independent distributor, TomatoElec provides inventory support, original component sourcing and BOM sourcing services for global customers.
