R5524 Series
USB Nch High-side Switch IC

Product Specifications

The R5524 Series are CMOS-based USB high side switch IC. R5524 is a protection IC used in power line of USB with built-in current limit circuit, thermal shutdown circuit, and under-voltage lockout circuit (UVLO). R5524x001A/002A has the built-in latch-off type over-current limit circuit. When the over-current is detected, the protection circuit becomes active and the switch-transistor is turned OFF. R5524x002A/002B and R5524N004A have the built-in over current protection circuit as the constant current type. It detects as the over-current condition, if the current flows as the ITH defined. Then operating the switch transistor to limit the output current to be the constant current defined by the ILIM. The R5524 is offered in a small-sized 5-pin SOT-23-5 package. It is also offered in a tiny 6-pin DFN(PLP)1820-6 package for consumer applications.
