RCU:电调天线的外置控制单元,天线内部使用了可机械调节的多路移相器,通过控制这些移相器来控制电调天线的下倾角度。在天线内部使用了可机械调节的多路移相器。RCU由驱动马达、控制电路与传动机构构成。其中,主控电路供电稳定尤为重要,SGM811-SXKA4/TR复位芯片可监测电压包括1.8V/2.5V/3V/3.3V/5V,即使供电电压低至1V时也可保证复位有效性,因此可以应用于控制电路的主控电源部分的监控。

    

SGM811-SXKA4/TR是一颗可支持手动复位输入,可在上电、断电及掉电情况下产生复位信号的复位IC。以下是SGM811-SXKA4/TR的关键参数:

    

SGM811-SXKA4/TR的应用优势:

1、支持手动复位,可减少不受控系统所带来的风险和破坏,提供系统的稳定性。

2、低功耗:静态工作电流典型值13μA,满足基站天线RCU要求低功耗需求。

3、SOT-143超小型封装,可有效节省PCB设计面积。

4、内部集成了精准的电压参考电路,可以精准的监测电源电压达到复位阀值时产生复位信号。

    

下图是SGM811-SXKA4/TR的典型应用电路,可以提供参考:

图1 SGM811-SXKA4/TR的典型应用电路

    

综上,SGM811-SXKA4/TR可以应用于基站RCU单元控制电路的主控电源部分的监控。
