R5523N SERIES USB HIGH-SIDE POWER SWITCH NO.EA-168-180516 OUTLINE The R5523N is a high-side MOSFET switch IC for Universal Serial Bus (USB) applications. Low ON Resistance (Typ.130m) and low supply current (Typ.20 A 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. FEATURES Built-in P-channel MOSFET Switch Supply Current Typ. 20 A (at Active Mode) Switch ON Resistance Typ. 130m Output Current Min. 500mA Flag Delay Time Typ. 10ms.
