AT42QT1244-MU OverviewPackages are made with materials from Tray. Surface Mount is needed to mount it on the PCB. 32-VFQFN Exposed Pad is extremely popular in the electronic industry due to its low package cost. Providing the 3V~5V Supply Voltage ensures the device's normal operation. There are inputs of Up to 24. In standard grade applications, it is classified as Type Buttons. You should keep it at -40°C~105°C at all times when it is operational. Due to its high cost-down performance ratio, the QMatrix™ Series provides the best value on the market. The current supply for this system is provided by 6.6mA. Part resolution is 10 b. In LED drivers, channels -- are used. It is set to 6.6mA for its supply current. The gadget's main component is characteriAT42QT1244ed by the number AT42QT1244. There must be more voltage present in the supply, Vsup, than volts consumed, 3 V. The supplier device comes in package 32-QFN (5x5). The Supply Voltage (Vsup) reaches maximum value when 5 V is reached. During reflow, 260 is the peak temperature. Over the 24 channel, data is transmitted. In addition to the 32 pin, there are some other uses as well. There is a 3, 5 V voltage required for its operation. The subcategory Sensors can be used to categoriSensorse it.
