ML9470是液晶显示驱动器,可直接驱动多达80段(静态展示模式)和高达160段的(1/2占空比的动态显示模式)液晶显示屏。
该芯片具有良好的高抗干扰性,宽泛的工作电压(3.0 to 5.5 V)和工作温度(-40 to + 105°C),被广泛的应用于汽车系统、AV产品、自动化仪表流量显示等。
工作范围
电源电压:3.0至5.5 V
工作温度范围:-40至+105°C间
段输出
可以显示静态显示模式:最多80段。
1/2占空比:可显示多达160段。
简单的接口与微机
内置通用信号发生器
输入数据和输出数据之间的一个一一对应
当输入的数据是在“H”电:显示的推移。
当输入的数据是:在“L”电平显示熄灭。
可级联
可与外部的共同信号同步
作为一个输出扩展适用
LCD驱动电压可以调整组合的VLC1和VLC2
封装
100引脚QFP(QFP100个P-1420-0.65-BK)
The ML9470 is a LCD driver which can directly drive up to 80 segments in the static display mode and up to 160
segments in the 1/2 duty dynamic display mode.
FEATURES
• Operating range
Supply voltage : 3.0 to 5.5 V
