ST STUSB4710 USB供电( PD)控制方案
ST公司的STUSB4710是USB供电( PD)控制器,集成了放电通路,能在Type-C™配置通路引脚(CC)通信,以判断对所需要的消费设备提供一定的功率源.器件不用MCU就能处理连接到UFP或DRP,完全和USB Type-C™ rev 1.2以及USB PD rev 2.0兼容,主要用在计算机,消费类或手持消费类电子的AC适配器和电源,智能插座和适配器,电源集线器和坞站,显示器和任何的Type-C源器件.本文介绍了STUSB4710主要特性,功能框图以及降压拓扑和反激拓扑应用电路,以及评估板STEVAL-ISC004V1主要特性,框图,电路图,材料清单和PCB设计图.
The STUSB4710 is a new family of USB power delivery controllers communicating over Type-C™ configuration channel pins (CC) to negotiate a given amount of power to be sourced to an inquiring consumer device.
The STUSB4710 addresses provider/DFP devices such as notebooks, tablets and AC adapters. The device can handle any connections to a UFP or DRP without any MCU attachment support, from device attachment to power negotiation, including VBUS discharge and protections.
The STUSB4710 is an autonomous USB power delivery controller optimized as a provider. It offers an open-drain GPIO interface to make direct interconnection with a power regulation stage.
