I am new to designing .
I am palnning to use tps 65090 for an application
where in I require to run the system for 1/2 hour after power off
for this I am planning to use this Ic . I am planning to use a 2s li ion battery (net voltage 7.4 V), which will be getting charged till the main supply is available.
my requirements is to supply with
two 5v 800mA ,
one 5V 1.2 A
one 5v 1A . that is a total of 3.8A
1) I know that while using li-ion battery one must monitor the temperature and according to that program the charging current and voltage in this IC there are two temp sensor input pins . in Evm user guide i found that two thermistors are being used are those enough for the design .
2) there is an inward directed arrow like box tagged Ts1 what is it is it temp sensor input . i am not clear about that symbol.
3) please explain me this symbol .
please help me with this .
