The CH7231A supports the USB Type-C

Electronically Marked Cable (E-Marker). The device

is designed to follow the USB Type-C Specification

1.2, the USB Power Delivery Specification Revision

2.0, Version 1.3 and USB power delivery

specification revision 3.0, version 1.1*. The

CH7231A is a low cost semiconductor device and

can help the cable manufacturer easily enabling the

USB Power Delivery feature required by USB TypeC E-Mark cable. In order to reduce the cost of the

cable material, The CH7231A integrates all necessary

components and circuits, such as LDO, clock

generation, isolation circuit, Ra, etc. The on-chip

embedded flash allows cable to store VDOs

commands specified by the Power Delivery

specification that to be used for communication

between provider and consumer.
