Production information

USB Power Delivery Controller



EJ899I is a USB Power Delivery (PD) controller, which integrates 6:4 MUX to reduce component count and PCB space, it is compliant with USB Power Delivery Specification Revision 3.0. The PD controller could negotiate voltage, current and direction with PD link partner to transfer up to 100W of power over Type-C connector and cable.
The EJ899I can support USB PD Alternate mode especially for Display Port application which is compliant with VESA DisplayPort Alt Mode on USB Type-C Standard v1.0a specification
