BU26507GUL数据手册集成电路（IC）的LED驱动器规格书PDF

描述 Description

BU26507GUL is “Matrix LED Driver” that is the most suitable for the cellular phone. It can control 5x6 (30 dot) LED Matrix by internal 5-channel PMOS SWs and 6-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. It adopts the very thin CSP package that is the most suitable for the slim phone.

特性 Features

• It has 5-channel PMOS SWs and 6-channel current drivers with 1/5 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)(ISET=100kΩ)
• The current drivers can drive maximum 42.5mA/Line(ISET=47kΩ)
• 64 steps of the luminance control by PWM (common setting for all dots)
• Easy register setting by A/B 2-side map for each dot.
• Automatic Slope function
• Cycle time, Slope time can be set for each dot.
• 8-direction automatic scroll function.
