R5523N Series

Data Sheet * Flyer

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.
