BU26507GUL中文资料LED Driver with I²C Compatible and 3-wire Serial Interface for 5×6 LEDs in Dot Matrix数据手册ROHM规格书

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.

简介

BU26507GUL属于集成电路（IC）的LED驱动器。由制造生产的BU26507GULLED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。
