VL103是一款高度集成的節能單芯片顯示端口Alt-mode和Power Delivery 3.0控制器，適用于USB-C設備，設計用于USB-C視頻適配器和USB-C多功能對接站等應用。v103集成了USB-C充電UFP，可實現DP切換模式視頻輸出功能，檢測到外接電源后，可同時對連接的PD主機充電。集成的第二個USB-C DRP既可以連接USB-C電源適配器為PD主機充電，也可以連接USB-C設備訪問數據傳輸。集成了D+/D-充電ePHY，支持使用D+/D-引腳進行協議握手的充電器。VL103的設備策略管理器可以在DRP和UFP之間協商電源規則，然后實現電源充電。支持電池無電模式下對主機充電，支持PD3.0快速角色切換。內置SBU1/SBU2交換機，支持USB-C轉接線功能。實現USB公告牌設備功能，滿足“VESA DP Alt-Mode on USB Type-C”規范。VL103還支持智能自動待機功能，當所連接的接口處于空閑狀態時，自動進入深度省電模式，適用于智能手機配件。

內置微調RC振蕩器，線性穩壓器，Vbus電壓檢測器和Vbus電流檢測器，VL103可以完美地工作在電源輸入，無論是從Vconn電源或從Vbus電源，并可以監測異常的電源行為。高達11 GPIO引腳可用于電源放電控制，電源開關控制，數據開關控制，或其他特殊應用用途。SPI接口支持外接SPI flash或與VLI Hub控制器共享SPI flash進行固件升級。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.
