USB HIGH-SIDE POWER SWITCH
The R5524N series is CMOS-based high-side MOSFET switch ICs for Universal Serial Bus (USB) applications. Using Nch FET as a switching transistor, low ON resistance (Typ.100mΩ) and reverse current protection is possible.
An Over-current limit circuit, a thermal shutdown circuit, and an under voltage lockout circuit (UVLO) 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.
In order to support easy power-line design, the over-current level is highly accurate.
The R5524N 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.
