LED Driver with I²C Compatible and 3-wire Serial Interface for 7×17 LEDs in Dot Matrix - BD26503GUL
BD26503GUL and BD26503KS2 is “Matrix LED Driver” that is the most suitable for the cellular phone and home electric appliances. It can control 7x17 (119 dot) LED Matrix by internal 7-channel PMOS SWs and 17-channel LED drivers. It can control the luminance and firefly lighting of the LED matrix by the setting of the internal register. It supports SPI and I²C interface.
