Does TPS2065D (1A)/ TPS2001D (2A) power switch support Biadirctional Current Sense protect? do we have the description or plot supports in detail?
the current sensing protection scenario are
what is the current protection scheme in when system power off; and system power active,
Hi Peter,
For power on, forward current limit protection:
As current limit, it makes internal Mos working from linear region to saturation region to increase the Rds in order to current limit.
Please refer to current limit section on datasheet 8.3.4 for details application.
For reverse protection, TPS2065D and TPS2001D only guarantee reverse current blocking as disabled. Datasheet description as following:
The principle is as following:
Internal Mos is back to back which can block the reverse current by diode as disabled.

Thanks.
