Part Number: BQ2004E Hi Team, seeking some inputs.
Specifically related to the state of the charger, when the battery is absent. According to the datasheet, it enters a "pulse trickle charge" mode infinitely. What voltage and current in this state supplying…
Part Number: BQ2004E In order to shorten the operation time of the initial trickle charge and immediately carry out the operation test of the quick charge, the TM1 terminal is connected to GND while the Energized. Will the reliability of the IC deteriorate…
Part Number: BQ2004E 20 NiMHcells charging at 0.5C (TM1 high, TM2 float). Charges at C/8 for hold-off time (546 sec.), followed by C/2 charge, at the end of which charge goes to zero until battery cools to Thtf (40°C). It then finishes the top-off charge…
Part Number: BQ2004E Hello,
I have a problem with my supervision of charge. I use the BQ2004E in my system of charge
If I denied battery i have indication that buttery is Done (LED1) Also from time to time I had observed charge action state is different…
Part Number: BQ2004E With bq2004E , we have used a RSNS of 0.165E but the charge current goes over 1.7A (instead of ~1.3A). I have attached the schematic of the same. It would be helpful if you can provide all the variables on which charge current is dependent…

Please find the attached circuit and suggest me...
DCIN = 21V, 10 cell NimH,
problem is as soon as the power is ON both LEDs are ON(charge pending) and immediately after 2 to 3 seconds it will enter into fast charge mode.
fast charge…
