CPT007B-A01-GMR Overview
The packaging uses materials from Tape & Reel (TR). Using Surface Mount, it can be mounted on the PCB. Its low package cost accounts for much of 20-VFQFN's popularity in the electronic industry. In order to ensure its normal operation, it needs the 1.8V~3.6V Supply Voltage. A Up to 7 input is used. Standard grade applications are classified as type Buttons. The temperature should always be kept at -40°C~85°C during operation. Drivers for LEDs have Up to 7 channels. Current supply for the device is set to 180μA. This is constructed by terminating 20. As long as the pin number remains 20, the component is in good shape. Voltage supply, Vsup, must be greater than voltage demand, 1.8V. Vsup reaches its maximum at 3.6V.
