Hi everyone!
I'm interesting has anybody built NIMH charger with DS2711 chip?
I want to build parallel configuration as in page 7 of datasheet (see attachment), for charging 1 or 2 NiMH batteries of 2600 mAh each. If so, can you please tell me:
1) What transistors can I use as replacement for FCX718 ?
2) What to do with ICHG and IFB pins ???
3) Is it possible to charge 2 batteries with different capacity with different "user defined" currents at the same time (with the same current sensing resistor) - if yes -how?
Thanks in advance!
------------------------------
Forget everything I ask! Maxim doesn't send free samples to ordinary people anymore!!!
But if somebody knows for good, preferably PIC project for smart charging of SEPARATE 1 to 4 NIMH cells with, at least, indicator-LEDs, let me know!
TIA!
