EJ898A中文资料USB Power Delivery Controller数据手册eEver规格书

描述 Description

EJ898A is a USB Power Delivery (PD) controller which is compliant with USB Power Delivery Specification Revision 2.0. The PD controller can negotiate voltage, current and direction with PD link partner to transfer up to 100W of power over Type-C connector and cable.

EJ898A supports USB PD Alternate mode, especially Display Port application which is compliant with VESA DisplayPort Alt Mode for USB Type-C Standard V1.0 specification. EJ898A can streamline the implementation of DisplayPort solution with embedded HPD mechanism and support different pin assignments via GPIO pins.

EJ898A can be configured by serial EEPROM or system controller to select different modes. They are Provider, Consumer, Provider/Consumer and Consumer/Provider swap mode.

EJ898A integrates 3.3V to 1.8V LDO to reduce component cost and take advantage of limited PCB space.
