R5520H SERIES USB HIGH-SIDE POWER SWITCH NO.EA-091-130827 OUTLINE The R5520H is CMOS-based high-side MOSFET switch IC for Universal Serial Bus (USB) applications. Low ON Resistance (Typ.100m) and low supply current (Typ.20A at active mode) are realized in this IC. An over-current limit circuit, 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 R5520H is ideal for applications of protection for USB power supply.
