Nokia3310 alimentat dintr-o sursa externa

Recommended Posts

Salutare, Trebuie sa alimentez un Nokia3310 dintr-o sursa externa, fara baterie. Bateria are 4 pad-uri, 2 sunt plus si minus, iar altele 2 nu stiu ce sunt. Ideea este ca am incercat sa-i dau tensiune pe plus si minus ( 3.6-4V ) dar nu porneste decit cu bateria sa originala. Nu stie careva cum pot sa fac ca sa-l pornesc?Am incercat sa pun pe celelalte 2 pad-uri o rezistenta de 47K ( presupunind ca acolo este un termistor, si masurind cu ohmetrul este de 47K ), dar tot nu merge.Multumesc.

Nu a mers, in schimb am gasit prin incercari urmatoarea schema: un divizor rezistiv cu 6K2, 1K si 1K, astel incit sa creeze pe intrarile BSI si T tensiunile de 1V, respectiv 0.5V. Telefonul l-am alimentat cu 4V pe bornele Vbat si GND. Nu stiu deloc ce inseamna BSI si T ( poate ne zici tu ) dar asa a mers.
