Other Parts Discussed in Thread: BQ2002, LM317, BQ2002G

Hi,

Well, i was looking for a Ni-Cd battery charger IC & i found BQ2002 suffice my application requirement. But the problem is, i did not get the application circuit any where in the BQ2002 datasheet for the Ni-Cd battery charging.

Hence may i have a Application circuit(along with the charge termination control) for Ni-Cd battery charging to charge any number of cells but at least one.

Hi charles,

Well, thanks for the information.

Well i have gone through the EVM DV2002L2/TL2 Development Document. But i did not get how the pulse trickle charging & Top-off charging is controlled/done to battery from the schematic there in that document.

1) So could you please elaborate on Pulse trickle charging for TM Pin in the mode, [MID & also LOW] & top-off charging on 'LOW'??

2) And is LM317 a good solution for the voltage regulations for BQ2002G?
