i want to make a switch mode battery charger for li-ion battery of mobile.i need a circuit diagram and i want to use microcontroller to stop the charging automatically after some time and to stop charging if over temperature occurs You can use cheap dedicated chip for this purpose MCP73832. Complete circuit requir
hi. I need circuit diagram for mobile battery charger, model no. JT-B50500 or JT-USB07, REV. 1.0
You really need to find out what kind of bettery you've got first. Lithium Polymers can only be charged/recharged a certain number of times before they have to be changed. Most mobile phones I have examined have NI-MH. Good luck
I want to make transistorised Li-ion battery chrger for mobile phone. The Li-ion battery is 800mAh for samsung cdma cell phone.
help me design mobile phone charger with battery 9 v as
Hi all can we use the mobile phone charger as the battery charger? i'd a mobile phone charger with output 5.4V,1000mAh and a battery of 3.6V,800mAh. the battery is of 3x1.2V AAA battery. can we make a charger adding a (...)

Can some one point me to the right direction to design the wireless battery charger? Any information relates to tranformer design, switching frequency, driving circuit etc.. for this specific application will be greatly appreciated. Thanks Please what "wireless battery charger" means ???
Is there any one who knows the circuit of mobile battery charger for Siemns SL55? Or other mobile charger from other company?
i need some information for design battery charger for Nokia with source 3-12 Vdc. if you can help me.. thanx very much. please email to me at
This chip using USB only like a power supply. You can use it with any 5V stable DC current sources for charge li-ion batteries. If you need an example of use this chip, I will post a part of my project where I used it for a li-ion battery from mobile phone. This chip provides a stable current on deep recharge phase and then stable voltage on 4.1 l

Hi, I am looking for circuits of 20-30 Amp intelligent battery charger for deep cycle batteries. Thanks.
hi guys! i have designed a 24v,4A low cost battery charger works in simple constant current mode as stand alone.also it is possible to control its output current/voltage by a microP or even a computer port,if an a/d card is available. its docs (sch & pcb)in protel format is available. if u want it respond to this letter! :smil
Hi, I have a 12v car battery charger, that I want to try and adapt to use as a motorcycle battery charger, yes it can be used as it stands, but motorcycle batteries don't need 4-6 amps ramming into them, it will do the job, but I've been told they could boil the battery My idea is to reduce the current (...)
battery charger Display The Over-the-Top type of operational amplifier is ideal for use as a current sense for battery charger applications. The design described here can be used with chargers for rechargeable batteries (Lead/acid or NiCd etc).
PC battery charger An unused serial interface port can supply enough current to charge (or trickle charge) lowcapacity Nickel Cadmium (NiCd) batteries.
i need a simple li-ion battery charger (3.6 and 7.2 v)
I am want to trickle charge a single cell Lithum Polymer battery ( 3.7 ) volts from a solar cell ( as small as possible). I am looking for schematics or at least info on how to do this. I am not talking solar panel type voltage sources but rather like what you get on calculators. Any help is hugely appriciated. JJ

i'am searching for schematics of fast battery charger battery from moto NTN1171A the controller on the pcb is sc405730 and other device with unknown indication . help plkease
Dear all, I want to build a 9V Ni-MH battery charger with auto-cut-off, could anyone help?
It is easy,give you a sample: Well this would not work I don't think !! mobile phones contain their own charging circuit don't they So all that is needed is the correct voltage supply the phone will do the rest
8) Hi, any body worked on Ni cd battery chargers. please post some links on Microprocessor based battery chargers. Thanx in Ad. Rauol
Is it possible to use a European mobile phone charger in the USA with the proper adapter, of course? 73 de Chipslicer
hi to all i need a 3 NiMH battery charger schematic (smart) I make some search on internet and found Dallas's DS2700 ic other ic's use so many componets on ic and some of them doesnt have an application circuit on their pdf DS2700's bad property is it look to the temperature of the battery and at my circuit my battery (...)
Hello Comunity! I've attached the schematic in bmp format for all users who need a battery charger. As soon as possible I'm going to include the programm in asm of methodology for charger any quantity of batteries. The methods that I've used are 3: Dv, temperature, Maximum charging. Any doubt, refer a question here. Regards.

What is the best battery charger (schematic) for lead acid batteries?
I know this has been asked before.. but I never saw schematics or a follow up as to how it came out on some of the projects. So I was wondering how to go about making a solar panel battery charger for say a parallel of four 3.6-3.7 volt lithium ions. I know some say a microcontroller should be used, some not.... any ideas? ok sorry.. let me be a
