High-Speed USB 2.0 (480Mbps) DPST Switch with  
Overvoltage Protection (OVP)  
ISL54228  
Features  
• High-Speed (480Mbps) and Full-Speed (12Mbps)  
Signaling Capability per USB 2.0  
The Intersil ISL54228 is a single supply, dual SPST  
(Single Pole/Single Throw) switch that is configured as a  
DPST. It can operate from a single 2.7V to 5.25V supply.  
The part was designed for switching or isolating a USB  
high-speed source or a USB high-speed and full-speed  
source in portable battery powered products.  
• 1.8V Logic Compatible (2.7V to +3.6V Supply)  
• Low Power State  
• Power OFF Protection  
• COM Pins Overvoltage Detection and Protection for  
+5.25V and -5V Fault Voltages  
The 3.5Ω SPST switches were specifically designed to  
pass USB full speed and USB high speed data signals.  
They have high bandwidth and low capacitance to pass  
USB high speed data signals with minimal distortion.  
The device has two logic control pins (OE and LP) to  
control the SPST switches.  
• -3dB Frequency . . . . . . . . . . . . . . . . . . 790MHz  
• Low ON Capacitance @ 240MHz. . . . . . . . . . 2pF  
• Low ON-Resistance. . . . . . . . . . . . . . . . . . 3.5Ω  
• Single Supply Operation (V ) . . . . 2.7V to 5.25V  
DD  
The ISL54228 has OVP detection circuitry on the COM  
pins to open the SPST switches when the voltage at  
these pins exceeds 3.8V or goes negative by -0.45V. It  
isolates fault voltages up to +5.25V or down to -5V from  
getting passed to the other-side of the switch, thereby  
protecting the USB down-stream transceiver.  
• Available in µTQFN and TDFN Packages  
• Pb-Free (RoHS Compliant)  
• Compliant with USB 2.0 Short Circuit and  
Overvoltage Requirements Without Additional  
External Components  
The ISL54228 is available in 8 Ld 1.2mmx1.4mm  
µTQFN and 8 Ld 2mmx2mm TDFN packages. It operates  
over a temperature range of -40°C to +85°C.  
Applications*(see page 15)  
• MP3 and other Personal Media Players  
• Cellular/Mobile Phones, PDA’s  
• Digital Cameras and Camcorders  
• USB Switching
