I want to use this IC , so I will be able charge the battery while using my device .
and when I disconnect the charger the device will continue working and not reset\start over.
http://cds.linear.com/docs/en/datasheet/3652fd.pdf
this is the battery I'm using (can't change it):
LiPO battery
nominal :11.1V
Max Charge Volt:12.8
the charger I have is 12.6V 2A
now I have some questions :
1. I understand that PIn7 (V_FB) is the voltage to the battery,right?
so I need to change to value of the resistors to work on 11.1V
2. the NTC (pin8) - do I have to connect it to the battery ? or I can leave it not connected to nothing ? in the battery I do have a NTC wire. is it impotent?
3. I want to use the CHRG (pin4) so I will know when the battery is full ? so just to connect LED with 10K to it?
if there is a simpler\easy and ready solution for my needs - I will be more then happy to hear,
Thanks ,
