Users want to know if there is some hidden danger if they don't add pull-up resistors in the external circuit in PWR_EN PIN

    Hi Tony,

    There's no hidden danger if you do not use a resistor for the PWR_EN pin. If a resistor is necessary to implement your specific pull-up system then you may include one, but it is not a requirement for the PWR_EN pin itself.

    Keep in mind that the system will depend on the stability of your pull-up source. You do not want PWR_EN dropping below 1.2V during normal operation of the PMIC so the circuit design should be such that PWR_EN pull-up is not subjected to sudden voltage drops.

    Regards,
