Description
The R5527 is an N-channel load switch IC with low supply current, Typ. 40μA. R5527 realizes low on-resistance by using Nch transistor for the driver. In addition, R5527K001x has a reverse current blocking function at on/off state, and R5527K002x has a reverse current blocking function at off state. The R5527 is an ideal load switch IC to supply power from the battery to the load circuit. The R5527 is available in an ultra-small DFN(PL)1612-4D package which can achieve high-density mounting on boards.
