Additional Details:

The CYPD6137-40LQXIT supports USB Power Delivery (PD) 3.0, enabling devices to negotiate and deliver up to 100W of power over a USB-C connection. It integrates a robust load switch with comprehensive protection features, including overvoltage protection (OVP), overcurrent protection (OCP), and short-circuit protection. The integrated discharge path for VBUS ensures safe discharging of the bus voltage when the port is disabled. The device is configurable via I2C, allowing designers to customize the port behavior and power delivery profiles. Its low power consumption makes it suitable for battery-powered applications. The device is typically available in a QFN package, making it easy to integrate into compact designs.
