R5527 Series
Battery Power Line Switch IC (Load Switch IC) with Soft Start Function

Product Specifications

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.

PRODUCT LONGEVITY PROGRAM

R5527 series operate PRODUCT LONGEVITY PROGRAM (ten-year supply is maintained as of January, 2016).
This program has been introduced to help customers select the most appropriate part for applications that require long life cycles.


SELECTION GUIDE

The ON pin polarity and the auto-discharge function for the ICs are user-selectable options.

  • # … Specify a combination of the ON pin polarity and the auto-discharge function.
    A: “L” Active, without auto-discharge function at off state
    B: “H” Active, without auto-discharge function at off state
    C: “L” Active, with auto-discharge function at off state
    D: “H” Active, with auto-discharge function at off state

* Auto-Discharge function quickly lowers the output voltage to 0V by releasing the electrical charge in the external capacitor when the ON signal is switched from the active mode to the standby mode.
