VL103节能单芯片概述、工作原理及特性

VL103是一款高度集成的节能单芯片显示端口Alt-mode和Power Delivery 3.0控制器，适用于USB-C设备，设计用于USB-C视频适配器和USB-C多功能对接站等应用。v103集成了USB-C充电UFP，可实现DP切换模式视频输出功能，检测到外接电源后，可同时对连接的PD主机充电。集成的第二个USB-C DRP既可以连接USB-C电源适配器为PD主机充电，也可以连接USB-C设备访问数据传输。集成了D+/D-充电ePHY，支持使用D+/D-引脚进行协议握手的充电器。VL103的设备策略管理器可以在DRP和UFP之间协商电源规则，然后实现电源充电。支持电池无电模式下对主机充电，支持PD3.0快速角色切换。内置SBU1/SBU2交换机，支持USB-C转接线功能。实现USB公告牌设备功能，满足“VESA DP Alt-Mode on USB Type-C”规范。VL103还支持智能自动待机功能，当所连接的接口处于空闲状态时，自动进入深度省电模式，适用于智能手机配件。

内置微调RC振荡器，线性稳压器，Vbus电压检测器和Vbus电流检测器，VL103可以完美地工作在电源输入，无论是从Vconn电源或从Vbus电源，并可以监测异常的电源行为。高达11 GPIO引脚可用于电源放电控制，电源开关控制，数据开关控制，或其他特殊应用用途。SPI接口支持外接SPI flash或与VLI Hub控制器共享SPI flash进行固件升级。VL103可提供qfn48l (6x6x0.85 mm)， pin-to-pin兼容VL102-Q4和qfn32l (5x5x0.85 mm)， pin-to-pin兼容VL100-Q3。

VL103 is a highly integrated power-saving single chip DisplayPort Alt-mode and Power Delivery 3.0 controller for USB-C devices that designed for applications like USB-C video adapters and USB-C multi-function docking stations. Integrated USB-C charging UFP, VL103 can perform DP alt-mode video output functionality and simultaneously charging connected PD host once external power is detected. Integrated second USB-C DRP can either connect to USB-C power adapter to charge PD host or connect to USB-C devices to access data transfer. A D+/D- charging ePHY is integrated to support chargers using D+/D- pins to do protocol handshake. VL103’s Device Policy Manager could negotiate power rules between its DRP and UFP then enable power charging-through. Charging a host under dead battery mode and PD3.0 fast role swap are supported. SBU1/SBU2 switch is built-in to support USB-C cable flipping feature. USB Billboard device function is implemented to meet “VESA DP Alt-Mode on USB Type-C” spec. VL103 also support smart auto-standby that automatically entering deep power saving mode when connected interface are in idle state which is suitable for smart phone accessories.

Built-in trimmed RC oscillator, linear voltage regulators, Vbus voltage detector, and Vbus current detector, VL103 can work perfectly with power input either from Vconn power or from Vbus power and can monitor abnormal power behavior. Up to 11 GPIO pins are available for power discharge control, power switch control, data switch control, or other special application usage. The SPI interface can support external SPI flash or sharing SPI flash with VLI Hub controller for firmware upgrade. VL103 is available in QFN 48L (6x6x0.85 mm) that pin-to-pin compatible to VL102-Q4 and QFN 32L (5x5x0.85 mm) that pin-to-pin compatible to VL100-Q3.
