Applications
MTCH101-I/OT is used to implement single-button capacitive touch interfaces in consumer electronics, home appliances, and industrial control panels, replacing mechanical pushbuttons with a no-moving-parts alternative. The small SOT-23-6 footprint suits integration into compact PCBs in wearables, medical devices, and smart home accessories where board space is at a premium. Its current output makes it straightforward to interface with general-purpose microcontroller digital I/O pins without additional decoding logic.

Frequently Asked Questions
What output type does MTCH101-I/OT provide and how does it interface with a microcontroller?
MTCH101-I/OT provides a current output that can be directly connected to a standard MCU digital input pin, eliminating the need for additional level translation or decoding logic and simplifying the single-channel touch sensing circuit in a 6-pin SOT-23 package.
How compact is the MTCH101-I/OT package and what does that mean for PCB layout?
MTCH101-I/OT comes in a SOT-23-6 package with body dimensions of 2.9 mm length × 1.55 mm width × 1.1 mm height, allowing very dense PCB placement alongside other surface-mount components and making it suitable for wearable or handheld designs with minimal board footprint.
Is MTCH101-I/OT RoHS compliant for use in global consumer electronics markets?
Yes. MTCH101-I/OT carries a JESD-609 e3 lead-free finish code, indicating RoHS compliance and a halogen-free compatible surface finish, qualifying it for shipment into EU, Chinese, and other markets enforcing restrictions on hazardous substances in electronic equipment.
When should a designer choose MTCH101-I/OT over a capacitive touch controller with I2C or SPI?
MTCH101-I/OT is the right choice when only 1 touch input is needed and the design cannot afford the complexity of a multi-channel controller with serial interfaces. It requires no firmware configuration, connects directly to a digital input pin, and saves bus resources while fitting in a 6-pin SOT-23 footprint smaller than 3 mm.
