atoof Posted August 17, 2006 Report Share Posted August 17, 2006 hibefore looking in your circuit,i want to say that USB can give you 5v dc with max 500mA current onlyis that suitable to you??. atoof Quote Link to comment Share on other sites More sharing options...
Guest nanop Posted August 17, 2006 Report Share Posted August 17, 2006 know of any PS/2 chargers? Quote Link to comment Share on other sites More sharing options...
deft_touch Posted August 18, 2006 Author Report Share Posted August 18, 2006 yeah. 500mA is fine for me. I'm using this primarily for charging batteries overnight, so time isn't a concern. the chip can charge up to 2 batteries at once, but the circuit in the datasheet, i'm not sure if it could handle it.

MP Posted August 21, 2006 Report Share Posted August 21, 2006 Maxim has an application note regarding this. I suggest that you go through it and make sure you are meeting all the requirements.http://www.maxim-ic.com/appnotes.cfm/appnote_number/3607MP Quote Link to comment Share on other sites More sharing options...
