简介

目前的中高端可编程逻辑控制器 (PLC) 解决方案集成了强大的 FPGA 或 SoC,从而推动先进工业自动化设备的技术实现。 因此,为了满足这种高要求组件的电源定序需求,采用由一个通用型微控制器和六个分立的DC/DC 降压稳压器(配集成电源 MOSFET)组成的灵活配置,既可为各类 FPGA 和 SoC 应用程序提供可扩展的电源定序最终解决方案,又能确保其易用性并降低实施过程中的失败风险。

系统优势:

  • 通用电源,输入电压范围宽(4.5 VDC 至 24 VDC)。
  • 分立的DC/DC 降压稳压器易于实施。
  • 低 Iq LDO,可为微控制器电源提供固定输出电压。
  • 通用型 RL78/G12 微控制器,采用 32 引脚封装。
  • DataFlash 可实现参数的稳定数据存储。
  • 可灵活地延迟通电 (Power-ON) 和断电 (Power-OFF) 事件,并且这些延迟可编程。
  • 通过微控制器的 ADC 监测主输入电压。
  • 读取每个 DC/DC 转换器的“电源正常”信号。
  • 对集成了 10 位 ADC 的电源轨进行冗余监测,以检测电源轨变化,从而增强供电和整体系统的安全性。
