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.
