內(nèi)置微調(diào)RC振蕩器，線性穩(wěn)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(jiān)測異常的電源行為。高達(dá)11 GPIO引腳可用于電源放電控制，電源開關(guān)控制，數(shù)據(jù)開關(guān)控制，或其他特殊應(yīng)用用途。SPI接口支持外接SPI flash或與VLI Hub控制器共享SPI flash進(jìn)行固件升級(jí)。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.
