BQ2050

Other Parts Discussed in Thread: BQ2050

Hi ,

I am using BQ2050 in my project to indicate the charge capacity of LI-ION batteries used for mobiles...

Two 1390 mAH motorolla batteries are connected in parallel & am evaluating the BQ2050 LED indications...

I have calculated the PFC as said in datasheet & did the jumper settings , but still the LEDs are showing charging status some times & never showed any indication for discharging

But i can do charge my mobile connected to these batteries & confirmed the circuit is working & only the LED doesn't showed up

Please find attached my schematic conections

Thanks & Regards

    Can you do HDQ communication and check if Charge bit is actually getting set and does NACL & NACH registers increment or decrement during charging or discharging respectively.And also check if your LMD got programmed properly as per your calculations.
