Dell pa-10 схема

The memory is accessed using a 1 wire communication protocol known as «1-wire». So the DS2501 in the DELL AC Power Adapter contains the identification info of the power adapter. However the 19,5 Volt comes with 4.62 Amps (max). The energy released would most likely blow-up the poor DS2501. And in practice it’s not so hard to do this, just insert a screw driver in the power plug connecting the inner tube (19,5 Volts) with the identification pin.

This is described in the Dallas Semiconductor application note 177. For electronics enthusiasts that’s just a bit of fun with a soldering iron and a few low cost components.

The power adapter identification pin has a protective cap on one side. The PA-1900-02D REV-A04 examined here has 2 meters of unshielded blank wire directly connected to the DS2501 «1-wire» data pin.

Если у вас появится желание добавить отсутствующую здесь схему для дальнейшего совместного использования можете присылать схемы на и я обязательно размещу её в нужной категории. Also soldering the 19,5 volt white wire in this position requires it to be clipped pretty short to prevent naked +19,5 volt wire to touch the already naked identification wire. In this case it was not. Now looking at the specification of the DS2501 «1-wire» memory chip, the power for this chip arrives through the data wire. It’s called «parasite power» supply, feeding on the energy supplied by the «1-wire» communication signal.

When detached from the laptop it carries no signal, voltage, capacity or resistance. It seems like a dead wire leading no where.
