BU16501KS2

Datasheet LED Driver with I2C Compatible and 3-wire Serial Interface for 8×16 LEDs in Dot Matrix BU16501KS2 General Description BU16501KS2 is “Matrix LED Driver” that is the most suitable for Home Appliance. It can control 8x16 (128 dot) LED Matrix by internal 8-channel PMOS SWs and 16-channel LED drivers. It can control the brightness in each dot by the setting of the internal register. It supports SPI and I2C interface. Features  LED Matrix driver (8x16)  It has 8-channel PMOS SWs and 16-channel current drivers with 1/8 TDM timing driven sequentially.  Put ON/OFF (for every dot)  The current drivers can drive from 0 to 20.00mA current with “16” steps(for every dot)  The current drivers can drive maximum 42.5mA/Line (ISET=47kΩ)  64 steps of the luminance control by PWM (common setting for all dots)  Interface  SPI and I2C BUS FS mode (max 400 kHz) Compability.  For I2C mode, I2C Device address is selectable (74h or 75h).  Thermal Shutdown Key Specifications  Operating power supply voltage range: 2.7V to 5.5V  Oscillator frequency: 1.2MHz (Typ.)  Operating temperature range: -40℃ to +85℃ Package(s) SQFP-T52M SQFP-T52 W(Typ) x D(Typ) x H(Max) 12.00mm x 12.00mm x 1.60mm 12.00mm x 12.00mm x 1.50mm Applications Mobile phone, portable device, home electrical appliance, and general consumer equipment.
