USB-PD Sink Controller CH224K SOP-8

Beschrijving

Nowadays USB PD (Power Delivery) is the standard on most modern consumer products. This enables users to use a single power adaptor across various products making it much more economic. CH224K from WCH is an easy-to-use low-cost solution for integrating USB PD into developing products. It offers easy configuration and cost-effective design. CH224K is a PD source controller that will communicate with PD sources such as PD charges and negotiate the necessary power output up to 20V 5A. It supports PD3.0/2.0, BC1.2 and other boost fast charging protocols. It also supports the automatic detection of VCONN and analog E-Mark chips, with a maximum power of 100W. It also has features such as built-in PD communication module output voltage detection, over-temperature protection and over-voltage protection.
