USB HIGH-SIDE POWER SWITCH
The R5524x is a CMOS-based high-side MOSFET switch IC which conforms to the universal serial bus (USB) standard. The device is suitable for protecting a USB power source.
By using an Nch MOSFET with low On-resistance (Typ. 100mΩ) 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.
The R5524x is offered in a 5-pin SOT-23-5 package and a 6-pin DFN(PLP)1820-6 package (currently developing) which achieve the smallest possible footprint solution on boards where area is limited.
