... CCC depending on the charge level. The restriction of the SAA1501T is a maximum average charge current and a minimum momentary charge current of 0.6 A. The same formula is applicable for the discharge current. The discharge efficiency can now also be changed by R depending on the discharge current levels, but independent of the charge current ...

... SAA1501T checks whether power or load is connected again. This checking is synchronized by the sensing signal of the V/I converters. The SAA1501T can handle a DC charge current as well as a discontinuous charge current (SMSP charger). The load current can also interrupted, e.g. produced by a motor ...
