Ricoh R5520H USB High-Side Power Switch Datasheet
The Ricoh R5520H is a CMOS-based high-side MOSFET switch IC designed for Universal Serial Bus (USB) applications. It features a low ON resistance of typically 100mΩ and low supply current of typically 20µA in active mode. The device includes built-in protection circuits such as over-current limit, thermal shutdown, and under-voltage lockout (UVLO), along with a delay circuit for the flag signal to prevent misoperation due to inrush current.
