R5527K SERIES
3A Load Switch IC
NO. EA-312-150320
OUTLINE
The R5527K is an N-channel load switch IC with low supply current, Typ. 40µA. By using an Nch transistor as
a driver transistor, the features of low on resistance and the reverse current protection at on/off state are
realized. The R5527K is an ideal load switch IC to supply power from the battery to the load circuit. The R5527K
is available in an ultra-small DFN (PLP)1612-4D package which can achieve high-density mounting on boards.

Pin Description
ON/OFF Control Pin, Active High/Low
Switch Output Pin
The tab on the bottom of the package enhances thermal performance and is electrically connected to GND (substrate level).
It is recommended that the tab be connected to the ground plane on the board, or otherwise be left floating.
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.

ABSOLUTE MAXIMUM RATINGS
Electronic and mechanical stress momentarily exceeded absolute maximum ratings may cause the permanent damages
and may degrade the life time and safety for both device and system using the device in the field. The functional operation
at or over these absolute maximum ratings are not assured.
RECOMMENDED OPERATING CONDITIONS (ELECTRICAL CHARACTERISTICS)
All of electronic equipment should be designed that the mounted semiconductor devices operate within the recommended
operating conditions. The semiconductor devices cannot operate normally over the recommended operating conditions,
even if when they are used over such conditions by momentary electronic noise or surge. And the semiconductor devices
may receive serious damage when they continue to operate over the recommended operating conditions.
