The AT42QT1040-MMH is a capacitive touch sensor integrated circuit from Atmel, designed to detect touch through up to four inputs. It operates over a supply voltage range of 1.8V to 5.5V and features four integrated LED driver channels for direct LED indication. The device is housed in a 20-VQFN (3x3mm) surface mount package with an exposed pad for thermal management.
The sensor supports a supply current of 10mA typical and operates over a temperature range of -40°C to +85°C, making it suitable for industrial and consumer environments. The surface mount design enables compact PCB integration.
This part is intended for touch sensing applications requiring up to four keys with accompanying LED feedback. The QFN package provides a low-profile solution for space-constrained designs.
