MPR121QR2 Overview
The packaging uses materials from Tape & Reel (TR). Mounting it on a PCB requires Surface Mount. Low package costs are one of the reasons for 20-UFQFN's popularity in the electronic industry. 2V~3.6V's normal operation is guaranteed by the 2V~3.6V Supply Voltage. There is a need to use inputs of Up to 12. Standard grade applications belong to Type Buttons, Slider, Wheel. Temperature -40°C~85°C should always be maintained during operation. 393μA provides this system with its supply current. There are Up to 8 channels on the LED drivers. Using terminations of 20, it is constructed. 3.3V-volt power is always supplied to the component. Vsup must be greater than 2V. As Vsup reaches maximum, 3.6V is reached.
