PXIe嵌入式系统控制器的电源管理装置
摘要：
本发明公开了一种PXIe嵌入式系统控制器的电源管理装置，(1)机箱背板输出的PWRBTN_C#信号上拉至常3.3V电源(+3.3Vaux)后连接到嵌入式系统控制器核心处理模块的PWRBTN#信号端，其中+3.3Vaux是机箱提供的+5Vaux转换产生的；(2)核心处理模块输出的SUS_S3#通过三极管器件取反，然后上拉至+5Vaux后连接到机箱背板的PS_ON_C#的信号端；(3)机箱背板输出的PWR_OK_C信号上拉至+5V后输入双路三极管，然后上拉至+3.3V后连接到核心处理模块的PWR_OK信号端；该+5V和+3.3V是机箱电源按钮被开启时由机箱电源产生的。本发明结合机箱背板信号特点，通过在嵌入式系统控制器上设计电路配合机箱实现电源的智能管理功能。
摘要（英）：

The invention discloses a power supply management device of a PXIe embedded system controller, wherein, (1) after being increased to a regular 3.3V power supply (+3.3Vaux), a PWEBTN-C# signal output by a case back plate is connected to a PWRBTN# signal terminal of an embedded system controller core processing module, wherein the +3.3Vaux is generated by conversing +5Vaux supplied by the case; (2)a SUS-S3# output by the core processing module is negated by a triode device, and after being increased to +5Vaux, the SUS-S3# is connected to a PS-ON-C# signal terminal of the case back plate; (3) after being increased to +5V, a PWR-OK-C signal output by the case back plate is input into a dual-path triode, and connected to a PWR-OK signal terminal of the core processing module after being increased to +3.3V; the +5V and the +3.3 are generated by a case power supply after a button of the case power supply is turned on. In the invention, by combining with the signal characteristics of the case back plate, the intelligent management function of the power supply is realized via designing a circuit fitted case on the embedded system controller.
