TI TPS65983USB Type－C和供电(PD)控制方案
TI公司的TPS65983是USB Type-C和供电(PD)控制器,电源开关和高速多路复用器,可在USB Type-C连接器中提供电缆插入状态和方向检测.根据电缆检测,器件采用USB PD协议在CC线上进行通信,完成电缆检测和USB PD协商后,器件会选择适当供电路径,并配置内部和外部多路复用器的交替模式,主要用在Thunderbolt 3(USB-C)接口设备.本文介绍了TPS65983主要特性,功能框图,Type-C和PD充电器应用图以及评估模块TPS65983EVM主要特性,电路图,材料清单和PCB设计图.
The TPS65983 is a stand-alone USB Type-C andPower Delivery (PD) controller providing cable plugand orientation detection at the USB Type-Cconnector. Upon cable detection, the TPS65983communicates on the CC wire using the USB PDprotocol. When cable detection and USB PDnegotiation are complete, the TPS65983 enables the appropriate power path and configures alternatemode settings for internal and (optional) externalmultiplexers.
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 PDcontracts by adhering to the specified bi-phase marked coding (BMC) and physical layer (PHY) protocol.
