R5524 Series
USB High-side Power Switch / Load Switch
Description
The R5524 Series is a CMOS-based high-side MOSFET switch IC which conforms to the universal serial bus (USB) standard. It can also be used as a load switch IC with protection function. By using an Nch MOSFET with low On-resistance (Typ. 100 mΩ) as a switching transistor, the device can provide low dropout voltage. Internally, the device consists of an overcurrent limiting circuit, a thermal shutdown circuit, an undervoltage lockout (UVLO) circuit and a reverse current protection circuit. The device also consists of an internal delay circuit to prevent the output of false flag signals caused by inrush current. To achieve simplification of layout design, the overcurrent detection accuracy has been improved.
