STMicroelectronics STMicroelectronics STAP08DP05/STAP16DPPS05/STAP16DPS05 LED 显示驱动器集成电路

STMicroelectronics STAP08DP05/STAP16DPPS05/STAP16DPS05 LED 显示驱动器是单片低压低电流 8 位或 16 位移位寄存器，用于 LED 面板显示屏。每个器件包含一个 8 位或 16 位串进并出移位寄存器，向 8 位或 16 位 D 类存储寄存器馈送信号。在输出阶段，8 或 16 个稳压电流源提供从5-100mA (STAP16DPPS05 为 3-40mA)的恒定电流以驱动 LED。检测电路可检查输出线路上可能发生的 3 种情形：短接 GND、短接 VO 或开路。数据检测结果载入移位寄存器并通过串行线路输出移出。3.3V 的电压供电对于任何微控制器连接 3.3V 的应用都非常有用。

The STMicroelectronics STAP08DP05 is available in a TSSOP-16 package. The STAP16DPPS05 and STAP16DPS05 are offered in an HTSSOP-24 package. All three devices are AEC-Q100 qualified for use in automotive applications.
