what should i connect to VBUS\_FET\_EN?

@copilot what should i connect to VBUS_FET_EN?
24d

copilot

The VBUS_FET_EN pin on a USB Type-C port controller, like the CYPD3177-24LQXQ, is typically used to control an external power switch or Field-Effect Transistor (FET) that is responsible for enabling or disabling power on the VBUS line (the main power line in USB connections).
Here's a typical connection setup for VBUS_FET_EN:

  • VBUS_FET_EN is connected to the gate of a P-channel MOSFET or the control pin of a power management IC (PMIC). This connection allows the USB Type-C controller to manage power delivery.

  • Connect the source of the P-channel MOSFET to the power supply (typically the input voltage or VBUS_IN pin, like VBUS_IN).

  • Connect the drain of the P-channel MOSFET to the VBUS line that leads to the USB Type-C connector.

Assumptions:

  • I assume you are using a P-channel MOSFET for power switching.

Please let me know if you have any additional specifications or constraints, and I can provide more detailed guidance!

can i leave this pin unconnected at all?
24d

copilot

Leaving the VBUS_FET_EN pin unconnected is not recommended if you intend to use the USB Type-C controller for managing power delivery. The VBUS_FET_EN pin is designed to enable the control of the VBUS voltage through an external switch (such as a MOSFET or PMIC).
If the pin is left unconnected, the USB Type-C port controller may not be able to properly control the power flow to the VBUS line, which could lead to issues in power management or result in non-compliance with USB specifications.
However, if you have verified that your application does not require dynamic control over VBUS power (and this is compliant with your application's power requirements and USB standards), you might consider leaving it unconnected. Still, I recommend:

  • Reviewing the controller's datasheet for guidance on how floating pins are handled.

  • Ensuring power delivery requirements are met and safety, functionality, and specification compliance are not compromised.

If you have a specific application or scenario in mind, please share more details so I can provide more tailored advice.

i want to output 20v constant from my usb -c, do i need to unconnect this pin?
24d

copilot

To output a constant 20V from your USB-C port, you generally wouldn't leave the VBUS_FET_EN pin unconnected. Instead, you'll use it to control an external power switch, such as a MOSFET, to regulate the 20V output on the VBUS line.
Here's how you can ensure a constant 20V output:

  1. VBUS Power Source: Ensure that your power source can provide a stable 20V and the necessary current as per your requirements.

  2. VBUS_FET_EN Control:

    • Connect VBUS_FET_EN to the gate of a P-channel MOSFET.

    • The source of the MOSFET connects to your 20V supply.

    • The drain of the MOSFET should be connected to the VBUS line of your USB-C connector.

  3. Configuration: The USB-C controller should be configured (via firmware or settings) to assert the VBUS_FET_EN signal when the USB-C device is connected or when power delivery negotiation is complete if applicable. This ensures that VBUS is provided when needed and prevents back-powering without a proper handshake.

Leaving VBUS_FET_EN unconnected would prevent the controller from enabling power to the USB-C port effectively. Ensure your configuration supports constant 20V output safely and in accordance with USB Power Delivery (PD) specifications.
If you have specific requirements or constraints, please let me know for more tailored advice!

I believe you're referring to a feedback voltage in a closed-loop control system. This is an important concept in electronic devices and systems.
Feedback voltage is the portion of the output voltage of a circuit or system which is routed back and used as input. It's often used in amplifiers and control system where it helps to stabilize the system and to reduce the overall gain.
In context of voltage regulation, such as in a power supply or a voltage regulator, the feedback voltage is used to improve the regulation accuracy. It's compared with a reference voltage to generate an error signal that drives corrections in the output voltage. This feedback loop aids in maintaining a constant output voltage even if the input voltage or load current change.
In your project, if a feedback voltage is implemented, it would typically be connected in a way so that it's taken from the voltage output of your IC, then sent to the IC's control pins.
Unfortunately, your textual schematic doesn't provide enough information to specify where a feedback voltage might come into play. Please provide further details if possible.
