USB HIGH-SIDE POWER SWITCH
R5523N SERIES

R5523N_E/2006/05/12
DESCRIPTION
The R5523N is CMOS-based high-side MOSFET switch IC for Universal Serial Bus (USB) applications.
Low ON Resistance (Typ. 130m
) 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 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 is ideal for applications of
protection for USB power supply. Since the package is small SOT23-5, high density mounting on board is
possible.
