I bought and assembled a 3A battery charger with this IC but when testing with a half charged LiPo cell (it was at 3.4V) the charger didn't behave as expected. Both the STAT and the PG leds were high, and the current going into the battery was only 0.2A. Now I'm trying to figure out if either my assembly, as the schematic shown bellow, is wrong, or if I made a mistake while soldering the components, can anyone help me?
I'm feeding it with a lab power supply and monitoring the batteries temperature, and applying thermal and over/under voltage protection with an external circuit , is there any problem with how i handled the supposed USB interface and the TS?
Thanks in advance
