Part Number: BQ2003 Hello,
I am using this charger IC to charge NIMH cells. Can you please suggest me, what provision shall i provide to test the charging circuit without connecting the battery. I have given a provision of a 2 pin jumper at CHG pin…
Hi Murugavel,
What is battery voltage sensed by BQ2003 when CHG status indicates charge complete? Can you show a waveform of charge current, CHG, and vbat (sensed by BQ2003)?
Part Number: BQ2003 We are having difficulty starting a new charge cycle while in top-off mode by toggling the CCMD pin with a 1ms pulse.
Is there any reason that this should not work?
Datasheet says that this should start a new charge cycle. Item…

Hi Peter
I'm not exactly answering your question, but what we mostly do here in our projects using BQ2003, is the usage of a double pole relay to:
1 - Short circuit the shunt to prevent the problem you are mentioning;
2 - Desconnect the battery…
Hello Manjunatha
I'm facing the same problem here using BQ2003 in a circuit similar to yours, and I can give you some tips that aparently (i'm testing continuously to check stability) are solving the problem. I'm trying to charge a 12Vx2500mAH pack…
