Battery Management Team,
I'm helping a customer who is looking to design a simple DC/DC NiMH battery charger circuit. The problem is, the battery is a single enclosed pack of 20 cells in series. It’s 24V nominal, 300 mAhr. Do we have any ICs that can work at that range? The charge algorithm cannot be a low rate trickle charge – ideally in 3-4 hours it could charge one up. Linear is preferable but switchers can work too.
I found this post from several years ago but wanted to see if there are any more recent developments.
Thanks!
