LTC4155 without NTC

Hello,

For a project I'm using a LTC4155 with wall power supply, USB and Battery.

The problem is that my battery doesn't have a NTC so the LTC4155 says NTC too cold (Subaddress 0x03 D7-D5) and my battery is never charged...

 

I tried to connect a 100K resistor between NTC pin and GND but if I disconnect my battery, the LTC will try to charge it and the Load voltage (VOUT) will fall down and all my system will reset.

 

Do you have a solution ?

 

Many thanks and best regards,

 

Damien
