AT42QT1040-MMHR Overview
The packaging uses materials from Tape & Reel (TR). For mounting on the PCB, Surface Mount is used. Despite its low package costs, 20-VFQFN Exposed Pad enjoys a significant amount of popularity in the electronic industry. In order for it to operate normally, it requires the 1.8V~5.5V Supply Voltage. There is a need to use inputs of Up to 4. Standard grade applications belong to Type Buttons. In order for it to operate properly, it should always have a temperature of -40°C~85°C. Featuring the best cost-down performance ratio on the market, the QTouch? Series is the most cost-effective option. A supply current of 10mA is provided to this system. A LED driver's channel is 4. This is constructed by terminating 20. An 3.3V volt supply powers the component at all times. There must be more voltage present in the supply, Vsup, than volts consumed, 1.8V. At Vsup, maximum Supply Voltage (5.5V) is reached.
