The Microchip Technology QT60248-ASG is a digital charge-transfer QMatrix IC designed to detect human touch on up to 24 keys using a scanned X-Y matrix. It can project touch keys through various dielectric materials up to 5 cm thick, allowing for robust and sealed control panels resistant to environmental factors like humidity, dirt, and abrasion.
The device supports individual key sensitivity adjustment via a serial port and stores configurations in onboard EEPROM. Key features include adaptive auto self-calibration, drift compensation, and digital filtering for reliable sensing. It also incorporates continuous FMEA self-test diagnostics for critical applications.
With an SPI slave interface, the QT60248-ASG offers synchronous noise suppression and spread-spectrum modulation for high noise immunity. It supports mixed key sizes and shapes within a single panel. The IC is housed in a 32-TQFP package and operates over a temperature range of -40°C to 105°C.
Applications include automotive panels, machine tools, ATM machines, touch-screens, appliance controls, outdoor keypads, security keypanels, and industrial keyboards. Its design permits the construction of 100% sealed, watertight control panels.
