MTCH102/105/108
2, 5 and 8-Channel Proximity/Touch Controller Product Brief
Description
The Microchip mTouch
®
MTCH102/105/108 Proximity/Touch Controller with simple digital output provides an easy way
to add proximity and/or touch detection to any application. This device family implements capacitive sensors with active
guarding capability. The sensitivity and power mode can be configured through the MTSA and MTPM pins. The
MTCH102/105/108 devices also use an advanced optimization algorithm to actively suppress noise from the signal to
achieve reliable proximity/touch detection.
Features
• Capacitive Proximity and Touch Detection System:
- High Signal to Noise Ratio (SNR)
- Adjustable sensitivity with compensation for
different sensor sizes
- Multi-stage Active noise suppression filters
- Automatic environmental compensation
- Support for wide range of sensor shape and
size
• Simple I/O Interface with existing System
• Smart Scan Scheduling
• Threshold Hysteresis
• Flexible Low-Power mode
• Brown-Out Protection
• Operating Voltage Range: 2.05V to 3.6V
• Operating Temperature: -40°C to +85°C
Application
Light Switch
Portable Device Enabler
White Goods and Appliance
Office Equipment and Toys
Display and Keypad Back-Lighting Activation
