BQ24165: battery protector

Hello,

I am using a Lipo battery (3.7V) with BQ24165 for GSM application.

If I understood correctly, I have to add an external protector to avoid deep discharge of my Lipo battery. Something that cuts it off when Vbat<3V (as nothing is present in BQ24165 except VBATUVLO which closes the FET when vbat<2.5V, which is too low). Any hint on what should I add for my battery deep-discharge protection? 

Thanks
