What are the key features of MTCH105-I/ST?
- 5 independent capacitive touch sensor inputs with dedicated open-drain output per channel requiring no firmware
- Standalone operation with simple I/O interface enabling MCU-free touch button implementation in low-cost designs
- 14-pin TSSOP package with matte tin finish rated to 260°C peak reflow temperature for standard SMT assembly
- Self-calibrating touch sensitivity with noise immunity for reliable operation in industrial and consumer environments
What is MTCH105-I/ST used for?
The MTCH105-I/ST is ideal for appliance control panels, lighting switches, and consumer electronic interfaces where 5 independent touch buttons must be detected without an MCU-based firmware solution. Its simple I/O architecture allows direct LED or relay driving from each channel output, reducing BOM cost in dedicated touch-only panels. Industrial control bezels and white goods requiring durable sealed touch interfaces benefit from its capacitive sensing approach.

Frequently Asked Questions
How many capacitive touch channels does MTCH105-I/ST support and how are outputs structured?
The MTCH105-I/ST supports 5 independent capacitive touch input channels, each with a dedicated open-drain output that drives low when a touch is detected. This 1-to-1 channel-to-output mapping allows direct connection to indicator LEDs through 1 kΩ resistors or optocouplers without any MCU firmware for basic button panels.
Can MTCH105-I/ST operate without a microcontroller in a simple appliance button panel?
Yes, MTCH105-I/ST is designed for standalone MCU-free operation. Its 5 open-drain outputs can directly control up to 5 LEDs or small relays when the touch inputs are activated, making it suitable for washing machine button panels or oven control interfaces with 5 touch zones and indicator LEDs running from a 3.3 V or 5 V rail.
What are the soldering requirements for MTCH105-I/ST in automated SMT production lines?
The MTCH105-I/ST in 14-pin TSSOP package supports standard SMT reflow with a peak reflow temperature of 260°C held for up to 40 seconds. Its matte tin (Sn) terminal finish is compatible with SAC305 lead-free solder paste, meeting JEDEC J-STD-020 MSL requirements for automated pick-and-place assembly.
How does MTCH105-I/ST compare to firmware-based touch solutions for small button count designs?
For panels with exactly 5 touch buttons, MTCH105-I/ST eliminates the need for a general-purpose MCU running touch firmware, reducing system cost by removing a 32-pin MCU, crystal, decoupling network, and firmware development effort. The 14-pin TSSOP occupies roughly 5 mm x 4.4 mm and requires fewer than 10 external passive components for a complete 5-button touch interface.
