CH224K
by WCH(南京沁恒)
WCH’s CH224K is a USB Type-C Power Delivery sink controller used to negotiate a power request from a compatible source. It lets a downstream design handle USB-PD source interaction without representing that protocol as a collection of discrete schematic functions. The library download supplies an 11-pin symbol and the 11-pad ESSOP-10_L4.9-W3.9-P1.0-LS6.0-TL-EP footprint, including its exposed-pad land pattern. A corresponding 3D model is provided for package and clearance inspection. The converted library entry has been used by 2 ProtoFlow engineers in real designs. The complete verified CH224K entry can be opened directly in ProtoFlow.
