CYPD5137-40LQXIT

The CYPD5137-40LQXIT is a USB Type-C and Power Delivery (PD) controller from Infineon (formerly Cypress Semiconductor). It integrates a 32-bit ARM Cortex-M0 core, supporting USB PD 3.0 and Type-C specifications. Key features include:
- USB-C & PD Compliance: Handles power negotiation (up to 100W) and alternate modes (DisplayPort, etc.).
- Programmable: Customizable firmware for flexible system integration.
- Integrated Peripherals: ADC, GPIOs, and communication interfaces (I²C, UART).
- Applications: Chargers, docks, monitors, and other USB-C-enabled devices.
Packaged in a 40-pin QFN, it simplifies designs by reducing external components. Ideal for fast-charging and multi-function USB-C systems.
For detailed specs, refer to Infineon’s datasheet.
