Series Resistor Connected to EN

Hi support team,

I understand that the EN pin must have a series resistor of 15kΩ or more.

Is it okay to simply use a pull-up resistor as shown in the diagram below?

Hi Dice-K,

Thanks for reaching out.

As long as you are sure that the GPIO and PG pins are not internally biased (or in open-drain configuration), it can be directly connected to EN pin of the device.

Best regards,

Hi Excel,
Thank you for your reply.

Since GPIO and PG are open drain, I understand that there is no problem with the circuit as it is.

Best regards,
