Overview
The CYPD2122-24LQXI is a member of the EZ-PD CCG2 family, an integrated USB Type-C port controller. It features an ARM Cortex-M0 processor and a complete Type-C transceiver to manage Power Delivery (PD) negotiation and cable identification.
Why Choose This Part
This controller integrates the transceiver PHY and required termination resistors (Rp, Rd, and Ra) into a small 4mm x 4mm QFN package, reducing BOM count. It supports a wide supply voltage range from 1.71V to 5.5V and includes 32KB of flash for in-system firmware updates.
Applications
Electronically Marked Cable Assemblies (EMCA)
Integrated into active and passive USB-C cables to communicate cable capabilities and power ratings to the host.
USB-C Power Adapters
Acts as the PD controller to negotiate voltage and current levels between the power source and the sink device.
Dongles and Docking Stations
Manages the USB Type-C interface for video and data conversion accessories.
