    Default Switching power sources, battery charging

    Hi,

    I'm designing a home alarm system and need to be able to switch during blackouts between a 15VDC power source and a 12V battery. I have found this design using mosfets:

    I need to support 5A so I'm using IRFU6215 mosfets instead (150V 12A 110W). Comments and opinions appreciated.

    Robert


    EDIT: Changed to 15VDC source to remain above battery charging voltage.
