Hi all

I need try use mobile battery in my handHeld Prroject (for example nokya 8210 or other popular mobile battery)

can give me any help or datasheet of this battery ?

i see some of it internal circuit how use it for charging ?
 

Hello maziar,

if it is a Li-Ion battery the circuit in that package is for protectiong the battery against faulty connection and overcharge (don't use the battery without the protection circuit - for your own safty!). For charging a Li-Ion battery you can use standard Li-Ion charing ICs (e.g. Maxim, Linear Technology, TI, ...). Take care of the nominal voltage of the battery. For one cell it is 3.6 or 3.7V.

i see many of mobile battery have 3 pin interface two of it is battey output
but i don know other pin job ... ?

hi i open in plastic pack i see in plastic package have one cicuit this internal charger ?

data I/O pin (1 -wire interface)

No, battery monitor IC, unique serial number, temperature sensor, measures the battery voltage and current.

have you info how use it circuit ?
have any standard or datasheet about it ?
 

The third pin is sometimes a connection to an internal
NTC-thermistor for sensing the battery temperature at charging

i cheak internal circuit no only NTC i See two chip in battery then not only
ntc

for 1-wire standard and battery monitor datasheet's
go to Dallas Semiconductor, now at www.maxim-ic.com
 

A Li-Ion battery has at least 1 circuit.

1) Protection
A serious battery supplier won’t sell the battery without an IC
that’s protects against over/undervoltage and overcurrent.
Sometimes they also add a thermal fuse for overtemperture.
The overcurrent can also be a fuse.
This protection IC is mandatory, newer use a Li-Ion without it.

2) Charging
Then you can have some circuit for the charger,
usually a NTC thermistor or a 1-wire battery supervisor IC.
 

The other possible definition for the third pin other than the Positive and Negative Pin IS: Batter ID type pin, which is connected to a resistor network.
 

nokia battery pins:

B+, BSI (Battery Size Indicator), BTemp ( Battery Temperature), and B-...
 

Hi idk

thanx of info abouto nokia battry can you help me more to using it ?

(pin out diagram , and hard ware protocol)

i try read this data from MCU
