This question relates to its use on battery protection circuitry of LiOns. Basically i been looking at some chargers more specifically a re-conditioning pulse charger like a Motorola Impress (WPLN4111) as an example and some battery packs that work on this charger like the NuOn NU8923Li and its honeywell counterpart. I seen the circuitry that these packs use and aside from the caps, resistors, diodes, thermistor, mosfets i see an E-PROM (S-29X90A series - 8 pins) CMOS serial E-prom, now i seen these: https://www.electro-tech-online.com/custompdfs/2006/08/BATTERY_MANAGEMENT_8-1.pdf
my understading about e-proms is not deep at all... (**broken link removed**) .. just some reading i beeen doing ... but i guess i lack some more understanding..
my questions are can an E-PROM if program be viewed and copy that of a MAXIM chip... or its role is to talk to the radio or charger only and let another chip do the battery gauging/. i am not too familiar with these and i been looking for ways to read an E-PROM any suggestion how one could go about it ?... any help would be appreciated it ....
mhh i think that by pluggin in the device reads the memory and then knows that its plugged in to a charger... also the working hours could be stored in their if the product is sended to fabric or something..
