VL102-用于USB-C设备的DP Alt模式和PD 3.0控制器

VIA Lab’s VL102 is a highly integrated single chip DisplayPort Alternate 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, VL102 can perform DP alt-mode video out functionality and simultaneously enable charging connected PD host
once external power is detected. Integrated USB-C DRP can either connect to USB-C power adapter to charge PD host or
connect to USB-C devices to do data transfer. A D+/D- charging ePHY is integrated to support chargers using D+/D- to do
protocol handshake. VL102’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 fast role swap are supported. SBU1/SBU2 switch is built-in to
support USB-C cable flipping feature. USB Billboard device and USB-C bridge function are implemented to meet “VESA DP
Alt-Mode on USB Type-C” spec and let the USB host to communicate with PD products connected on downstream port. VL102-Q4 QFN48
 
Built-in required linear voltage regulators, Vbus voltage detector, and Vbus current detector, VL102 can work perfectly with
power input either from Vconn power or from Vbus power and can monitor abnormal power behavior. Up to 9 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 flash for firmware upgrades through USB Billboard device. VL102 is available in QFN 48L
(6x6x0.85 mm) green packages to fit small form-factor design.VL102-Q4 QFN48
