BU21009MUV-E2 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 32-VFQFN Exposed Pad's popularity in the electronic industry. In order to ensure its normal operation, it needs the 2.5V~3.3V Supply Voltage. A Up to 16 input is used. Standard grade applications are classified as type Slider. The temperature should always be kept at -40°C~85°C during operation. A part's resolution is 10 b. Drivers for LEDs have Up to 8 channels. Current supply for the device is set to 300μA. This is constructed by terminating 32. Voltage supply, Vsup, must be greater than voltage demand, 2.5V. This is included in the Surface Mount mount. There are 16 channels for transmitting data. It is provided for specific purposes with a 32 pin. In order for it to operate, 3V voltage must be supplied.
