TI TPS65982USB Type－C和PD控制器评估方案
TI公司的TPS65982是USB Type-C和PD控制器,在USB Type-C连接器中提供电缆插头和定位检测,采用USB PD协议通信.当电缆检测和USB PD协商完成,TPS65982将提供电源通路和配置模式,以用于供电,受电和供电/受电,提供500mA,1.5A或3A电源.主要用在笔记本电脑,平板电脑,坞站系统,充电器,USB PD使能的总线供电设备,DisplayPort, Thunderbolt™和HDMI.本文介绍了TPS65982主要特性,功能框图和几种应用电路,以及评估模块TPS65982-EVM主要特性,电路图,材料清单和PCB设计图.
The TPS65982 is a stand-alone USB Type-C & Power Delivery (PD) controller providing cable plug and orientation detection at the USB Type-C connector. Upon cable detection, the TPS65982 communicates on the CC wire using the USB PD protocol. When cable detection and USB PD negotiation are complete, the TPS65982 enables the appropriate power path and configures alternate mode settings for internal and (optional) external multiplexers.
The mixed-signal front end on the CC pins advertises default (500 mA), 1.5 A or 3 A for Type-C power sources, detects a plug event and determines the USB Type-C cable orientation, and autonomously negotiates USB PD contracts by adhering to the specified bi-phase marked coding (BMC) and physical layer (PHY) protocol.
