CYPD2122-24LQXIT

CYPD2122-24LQXIT is a Cypress (now Infineon) USB Type-C Power Delivery controller IC. It is designed to enable USB-C port functionality and PD negotiation in devices such as chargers, docks, adapters, and hosts.
Key points:
- Function: USB Type-C port controller with PD negotiation and CC line management, typically interfaced to a system MCU via I2C for configuration and status monitoring.
- Packaging: 24-pin LQFP/LQX-style package, industrial temperature grade (IT suffix indicates industrial operating range).
- Applications: Implementing USB-C PD in power adapters, charging devices, USB-C hubs/dock ports, and battery chargers.
- Interface and integration: Works with a host controller to establish power contracts; provides detection, protection, and control logic for safe Type-C operation.
- Why choose: Compact PD-enabled controller that reduces development time for Type-C implementations.
Note: For exact electrical specs, pinout, and PD capabilities, consult the official Cypress/Infineon datasheet and packaging documentation.

CYPD2122-24LQXIT features (concise):
