I'm trying to figure a way to switch a DPM from battery to battery in a 10 battery series string. At first I thought I'd do it manually using a small SMD 2 pole 10 position rotary switch but the only ones I've found at a reasonable price & size are coded (BCD). Then I thought it would be better to automatically scan. I bet there is a device out in chip land that could do the deed.
I would prefer to not go smart (i.e. PIC) or relays if possible. Something simple, small & cheap. Discrete FET switches would take up a fair amount of physical space which I don't have. Is there a 20 FET ASIC?
