Part Number: LM48100Q-Q1

Datasheet shows a 1.5KOhm pull up on _FAULT pin.

What is the min-max Rpu values supported on this pin? What is the typ/max current of this open drain output?

Hi, Eddie,

Sorry for the late response.

As mentioned in the datasheet ( 7.3.5 Open FAULT Output ), the pull-up resistor should be at least 1.5Kohms. There's no restriction for a higher resistor.

Regarding the open drain output current, the typical value is 3mA. There could be a max variation of 1mA.

Best regards,
Luis Fernando Rodríguez S.
