R5527 Series

Battery Power Line Switch IC (Load Switch IC) with Soft Start Function

  • Consumer
  • PLP
  • RoHS

The R5527 Series are CMOS-based battery power line switch IC. The Due to a soft start function, The R5527 can prevent an inrush current at startup. Therefore, the R5527 is the optimal as power supply switch of the battery power line switch for hand-held communication equipment. Due to a built-in N-channel transistor with low on-resistance of 45mΩ, the R5527 provides a low dropout voltage. In addition, a built-in reverse current protection circuit, the R5527 prevent a reverse current not only off state but also on state. Since the maximum rating of output current is 3A, it is able to use as a load switch of low on-resistance. The R5527 is available in DFN(PLP)1612-4D package.
