CH224K Description

Short technical summary and product information.

The WCH CH224K is a cost-effective USB Power Delivery (PD) Sink Controller that simplifies the integration of USB PD functionality into electronic devices. It is designed to communicate with PD sources, such as chargers, to negotiate power output up to 20V and 5A, supporting a maximum power of 100W.

 

This controller is compliant with PD3.0/2.0 and BC1.2 fast charging protocols. It automatically detects VCONN and analog E-Mark chips, facilitating seamless power negotiation. Key features include built-in PD communication, output voltage detection, over-temperature protection, and over-voltage protection, ensuring safe and reliable operation.

 

The CH224K offers flexible configuration options, allowing it to be used in stand-alone mode without a co-processor. The output voltage can be programmed using configuration pins, either with a single pin for simpler applications or with three pins for more control, which can also be managed by a microcontroller.

 

Applications for the CH224K include wireless chargers, laptop charging cables, small appliances, lithium battery packs, electric tools, and mobile power banks, making it a versatile component for modern power solutions.
