Seeking Advice on Pull-up Resistor Values for LTC4417 VALID Pins

[KarthiAru]

Hello everyone!

I'm currently working with the LTC4417 to manage power switching between batteries and USB in my circuit. I've noticed that the datasheet's application circuit recommends using 1M ohm pull-up resistors on the VALID pins, which seems unusually high. Does anyone have insights on why this specific value is recommended? If you've used this component, what pull-up resistor values did you choose? Any guidance or experiences shared would be greatly appreciated!

I would assume that the high resistor values are chosen for efficiency reasons, but would ultimately depend on the load they are driving i.e. the /valid signal.

Thanks. The /valid pins are directly connected to the STM33 MCU GPIO ports in my case.
