BQ27542-G1: TS input shared? or not used?

Hi there, 

I building a design based on the BQ27542 Fuel Gaeg and the BQ25619 Battery charger. 

I definitly needs the NTC connected to the Charger to handle charge current and voltage. 

So my first question is:

- Can the NTC be shared between the 2 devices? 

- If the answer is NO (which I suspect), what should I do with the TS pin of the BQ27542? Can it be left open? Where in the FW can we let the chip lnpw that the temperature is not monitored? 

Thanks in advance for your help,

Mickael
