EVAL-CN0581-EBZ

EVAL-CN0581-EBZ is a configurable USB-C power sink solution evaluation board. It is a standalone USB-C power delivery (PD) module that adds USB-C power sink capability to projects and devices, replacing traditional power jacks. Voltages of 5V, 9V, 15V, or 20V at currents from 0.5A to 5A are supported, and selected via dual in-line (DIP) switches. A hot-swap surge stopper with an ideal diode allows charging of large bulk bypass capacitors, and an enable output enables the downstream load after ramp-up is complete, while preventing reverse current during faults. No software control is required for operation; the preloaded firmware configuration reads the DIP switches and sets the power delivery object (PDO) voltage and current modes accordingly. Custom configurations can be optionally programmed via an I2C interface. Typical applications are smart speakers, power tools, wearables, cameras, IoT devices, VR headsets, gaming consoles, drones, and robots.

• USB Type-C power delivery standalone controller
• On-board DIP switches allowing customization of VBUS voltage and current settings
• Breadboard 2.54mm pitch pin headers for easy prototyping
• USB-C 1.3 compatible, PD 3.0 negotiation and messaging
• Surge stopper with reverse protection and fault detection
