Other Parts Discussed in Thread: BQ2004E Hi!
I'm using a BQ2004E and I'd configured the IC to work on mode Mode 1 and VSEL=0, charging a NIMH 9.2V battery. The TM pins configuration is: TM1=0 and TM2=1.
The Temperature sensor was calculated, to make…
Other Parts Discussed in Thread: BQ2004E Hi!
I'm using a BQ2004E in one circuit, and when I was reading its datasheet, I had one doubt.
It says on page 4 that the range for fast charge work is V_HTF < V_temp < V_LTF .
But on page 5, it says that…
Other Parts Discussed in Thread: BQ2004E , BQ2003 , BQ2004 Hello,
I've a little problem with my supervisor of charge. I use the BQ2004E in my system of charge.
When I put my batteries in my charger, it doesn’t detect them. I need to put high the…
Other Parts Discussed in Thread: BQ2004E Hello,
I'm using a charge circuit with bq2004e for a 8cell battery pack and i was checking the application note and found some questions,
on page 5 from http://focus.ti.com/lit/ug/sluu016a/sluu016a…
Part Number: BQ2004 Is there a limit to the input order of VIN and VCC of bq2004?
Normally it is VIN-->LDO (DCDC --> VCC this time). If batteries are present, I think the VCC will be powered first.
I attached block diagram. Could you please check…
Other Parts Discussed in Thread: BQ2004H , BQ2004 , BQ2004E Customer want to use only pulse trickle charge operation of bq2004, bq2004E, or bq2004H.
Is there way to unused fast charge operasion?
I think that external resister set for "always VTEMP…
Hi Dear, Thanks for ur response. Sorry to mention that the above timings are related to BQ2004E. I am using BQ2004H, the reference values on all the pins are OK. But the fast charge is terminated after some time but Battery never reached full charge.…
Other Parts Discussed in Thread: BQ2004E For the DV2004S1 demo board, would someone please confirm something for me before I implement the circuit? Question is about the voltage at the BAT+ pin, or the connection between L1 and C1. I know L1 is used to…
Part Number: BQ2004 I designed a battery charger with BQ2004E for 4 cells Nimh battery(10000mah). I found the charger will always stop fast-charge before it's completely charged and the time seems shifts in the table in datasheet. For example, I set TM1…
Other Parts Discussed in Thread: BQ2004E , BQ2004 , BQ2004H I am trouble shooting an older design using bq2004E. The problem is that fast charging never starts except when the powered is recycled, othewise the batteries are always discharged. The INH…
