R5523N SERIES
USB HIGH-SIDE POWER SWITCH
NO.EA-168-120921
OUTLINE
The R5523N Series is CMOS-based high-side MOSFET switch IC for Universal Serial Bus (USB) applications.
Low ON Resistance (Typ.130mΩ) and low supply current (Typ.20μA at active mode) are realized in this IC.
An over-current limit circuit, a thermal shutdown circuit, and an under voltage lockout (UVLO) circuit are
built-in as protection circuits. Further, a delay circuit for flag signal after detecting over-current, is embedded to
prevent miss-operation of error flag because of inrush current. The R5523N Series is ideal for applications of
protection for USB power supply. Since the package is small SOT-23-5, high density mounting on board is
possible.

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.
