Power Selector Switch

Power Selector Switch

R5528Z

Nowadays hand-held equipments such as smartphones and tablet PCs are able to charge not only from AC adapter and USB power but also from a new wireless charger method.

In such case, it is necessary that the PMIC selects between two charger circuits. This selector circuit can be made easily by using two R5528Z ICs.

The maximum output current of R5528Z is 3A, so it can be used in equipment using a large battery.
