Part Number: BQ2002 Hi,
I would like to ask you about the state transition diagram in Figure 2 of the BQ2002/F and BQ2002E/G datasheets. (question 1) The conditions for shifting from trickle charging to recharging are described as VCC for BQ2002/F and VBAT…
Part Number: BQ2002E Other Parts Discussed in Thread: BQ2002 Hello,
In the BQ2002E datasheet, it states that Starting A Charge Cycle can be initiated two ways, I am interested in the 2nd method, bringing the BAT pin below Vmcv (2.0V).
I am implementing…
Other Parts Discussed in Thread: BQ2002E Hello.
First, i apologize for my bad english, but i'm an italian guy.
I built a ni-mh charge battery with BQ2002E. I used the circuit similar to DV2002L2/TL2 (picture below). I used two different voltages: one…
Part Number: BQ34Z100EVM Other Parts Discussed in Thread: BQ2002E , BQSTUDIO , BQ34Z100-G1 Hello,
I am running into a problem with Steps 6 and 7 under "When no close Qmax value is known:" on page 2.
I start step 5 and see that the QEN and VOK bits…
Part Number: LM3405A Other Parts Discussed in Thread: BQ2002E , Hello,
I want to use the LM3405A as a constant current driver for NiMH cells. In my configuration, I have 2 NiMH cells, and a BQ2002E that regulates the battery charge profile. I want to charge…
Part Number: BQ34Z100-G1 Other Parts Discussed in Thread: BQ2002E , GPCCHEM , BQSTUDIO , , BQ34Z100 , GPCRA0 I still cannot get passed the initial Step 6 in "When no close Qmax value is known:". I have taken suggestion on similar threads and I believe…
I've tested your suggestion, but situation is the same. If I leave it in this semi-trickle mode, the spikes density decrease with the time and after .. arhm ... , let say 4-5 hours, the controller enters permanently in trickle mode.
Anyway, I've…
Part Number: BQ27220 Other Parts Discussed in Thread: BQ2002E , , BQ27210 , BQ34Z100-G1 , BQ34110 , BQ34Z100 , BQSTUDIO Hello,
My local TI sales rep has been working with the Battery Management Group to find a gas gauge solution for a 2-cell NiMH device I have…
Other Parts Discussed in Thread: BQ2002E , BQ2002 , LM317 Hello,
I have 4x 1.2V NiMh cells that need to be charged from a 4.7V-5V source (0.5A). Here is what I've learned so far by reading the doc and application notes on this website:
I need a fast…
