Description

With the continuous improvement from the previous generation of RotoPD, our RotoPD Pro leverages advanced power delivery protocols 3.1 to achieve a full specification output range— 4.5V to 48V at 240W max. The breakout board use a stand alone Power Delivery Sink controller to negotiate with your modern charger and provide different output voltage.

Standard trigger board can select fix voltage like 5V, 9V, 15V, 20V, and 28V. Centylab's RotoPD Pro unlock more advance mode in your USB-C power supplies like Programmable Power Supply (PPS) and Adjustable Voltage Supply (AVS), to provide even more granular voltage adjustment. The RotoPD simplifies power negotiation with USB-C adapters, handling the complex process of establishing power delivery contracts. The controller does all the heavy lifting of power negotiation and provides an easy way to configure over I2C, free your micro-controller from the complicated USB-C PD protocol.

Feature

• Input and output voltage range of 48V at 5A max
• On board buck for 5V output at 1A max, 0.4A continuous
• Support Qwiic or STEMMA QT in 3.3V Only
• Support PD3.1 EPR/AVS Up to 48V and SPR/PPS Up to 21V
• Certified USB PD3.1 v1.6 TID: 10062
• Integrated ESD and flyback diode protection
• Integrated NTC temperature monitoring
• On board VBUS switch (back-to-back NMOS)
• Current sensing from 0 to 5 A at ±2% accuracy up to 60C

Important Note

The 3.3V In is only for input power. This is the same voltage as the I2C digital communication line. RotoPD Pro only support 3.3V logic. Power is required for I2C communication.
