Battery charger

I ordered a sample 4011 chip from Linear to make a battery charger. I've found a few resources on the net, has anyone here made a Nimh charger? I did a search of the forums but didn't get any hits.

Thanks,

Steve

    Using a Quad 2-Input NAND Gate to create a NiMH battery charger?· Okay, yeah, I guess I could see that.· Perhaps a switching system (regulator) to charge it?· Driven by the 4011, of course...

    Ah, that would be the difference...Us Old-Schoolers see 4011 and think CMOS logic!· =)

    I'm glad I wasn't the only one going there...

    Tom,

    ·· No it's not just you...I have to double check part numbers these days to make sure it's equivalent to the old part and not something totally unrelated, as in this case.· The joys of being old-school...· =)
