Hi team，

what is the state of RESET pin when there is VIN, but EN=0?

Will the open drain MOSFET inside be switched ON and pull RESET pin LOW?

Hi Alan,

When En is low, there will be no switching and the buck will be "off"

Hi Rahil，

Thanks for your answer. My question is, when VIN is present, EN is low, is the MOS in RESET ON? And then does RESET pull to GND? Because the description in DS says that when EN is low, reset will pull low, I want to confirm whether this MOS pulls low and pulls to GND.

Hi Alan,

Rahil is on time bank and will respond next week when he is back in office.

Thank you for your patience,

Hi Alan,

The datasheet says that it will be pulled low.
