What TI Single Cel LiPo IC Charger to use?

 

Hello,

We are designing a tracking device and want to charge our device by USB and AC by same switch. What TI Battery Charger do you recommend me to use?.

1.- We have to charge a Li-Po battery of 1500 mAH (3.7V Nominal).

2.- We are looking for 1A charging by AC and 100-500 mAH by USB.

3.- If is possible price below $1.5 in +1k Quantities.

I know that exist many options but we prefer an expert opinion.

Many Thanks!!!
