I use LTC2952 in configuration B in many my circuits and it works flawlessly.
Now I have a task to create a prioritized power path controller not with a push button but with a rotary switch with "make before break" functionality. Due to some circuit restrictions I can't use a one shot pulse generator to create a valid push button event when a rotary switch changes its position from OFF to ON and vice versa (let's assume that in ON position switch can only pull down to ground and in OFF position it goes Hi-Z). I've modeled a case where device is turned on via a PB pin going low and I shut down the device via applying a zero to !KILL input when an external MCU detects that switch was turned to OFF position. I don't need !INT at all.
So my question is: is it ok to leave a PB pin low for an infinite time? Any drawbacks or surprises?
