USB Type-C Cable E-Marker Chip CH252

Overview

CH252 is a USB Type-C cable eMarker that supports USB Type-C 2.1 standard and USB PD 3.1 standard, and can be used for various Type-C cable related applications. The CH252 ships with a default configuration programmed in internally. The CH252L chip, CH252A chip, and the terminals and finished cables using CH252A all support update programming configuration data through a special programming tool. In addition to the default configuration, each CH252 also supports up to 5 times of configuration data update programming, and has a data lock function.CH252's factory default configuration data has a variety of options. The CH252 is USB-IF PD3.1 certified with TID number 9134.
