Controllers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pin configuration and packaging details. Ensure that the component meets the required environmental specifications for the intended operating temperature range before finalizing procurement decisions.

Controllers Selection Notes

Select this model for designs requiring full hardware implementation of USB PD 3.0 without external processors. Consider the 20-lead QFNW package for compact layouts. Verify compatibility with the target DC-DC regulator or opto-coupler feedback requirements for proper voltage regulation.

Controllers Part Context

This component belongs to the FUSB3307 series of USB Power Delivery controllers. It is designed as a highly integrated solution for power sources, eliminating the need for external microcontrollers by handling policy management and protocol layers internally.

Controllers Replacement Considerations

Check the manufacturer's datasheet for alternative part numbers within the same series that offer different power ratings or package options. Ensure any substitute maintains compatibility with the existing PCB layout and thermal requirements.

Controllers FAQ

How does the FUSB3307 handle VBUS discharge?

The device uses an internal discharge path controlled via the DISC pin, which connects to an external resistor to safely discharge VBUS within specified time limits during attachment events.

What protection features are included for the CC lines?

The FUSB3307 includes CC1 and CC2 over-voltage protection (CC_OVP) capable of withstanding up to 26 V, ensuring safety against high-voltage shorts on the configuration channels.
