hi Ubergeek63
thanks for this links.
i think the bq 2000 is exactly what i'm looking for.
is it possible to just use the Peak Voltage Option (without temp. control etc)?
"Peak Voltage (NiCd, NiMH)
The bq2000 uses a peak-voltage detection (PVD) scheme
to terminate fast charge for NiCd and NiMH batteries.
The bq2000 continuously samples the voltage on the
BAT pin, representing the battery voltage, and triggers
the peak detection feature if this value falls below the
maximum sampled value by as much as 3.8mV (PVD).
As shown in Figure 6, a resistor voltage-divider between
the battery pack’s positive terminal and VSS scales the
battery voltage measured at pin BAT." page 5 from the bq 2000 link you've send
there is one more thing which i forgot to mention: the +/- cable coming from the charger should maintain the power (3.6v) while charging so the object (in this case an led light) can still be operated while being charged.
is the peak voltager charging regulator still able to detect the battery status in this case?
thanks for advise, it is much appreciated as i am still a beginner in electronics.
