CEA-936A Charger标准

CEA-936A_Carkit ChargerCEA Charger Handling Basic chargers and basic car kits indicate their default current limits through the value of the resistor RACC_ID_DWN, between the ID and the ground, and through the data bus connection type (shorted or not shorted) (see the CEA-936-A specification).
