In our product we are powering the system from the LTC4011 as well as using the LTC4011 to charge the NiMH batteries.
We need a quick way to determine if we are powered from external voltage or the internal NiMH.
I believe that when the /READY line is active (LOW) that would indicate that the system is being powered from external power.
If the /READY line is inactive (HIGH) the system is powered from the internal batteries.
Is this a correct assumption?
