High-Speed USB 2.0 (480Mbps) Multiplexer with

Overvoltage Protection (OVP) and Overvoltage

Indicator Output

ISL54224

Features

• High-Speed (480Mbps) and Full-Speed (12Mbps)

Signaling Capability per USB 2.0

• 1.8V Logic Compatible (2.7V to +3.6V supply)

• OE/ALM Pin to Open all Switches and Indicate

Overvoltage Fault Condition

• Power OFF Protection

The Intersil ISL54224 is a single supply dual 2:1

multiplexer that can operate from a single 2.7V to 5.25V

supply. It contains two SPDT (Single Pole/Double

Throw) switches configured as a DPDT. The part was

designed for switching of USB data signals in portable

battery powered products.

The 6.5Ω switches were specifically designed to pass

USB high speed/full speed data signals. They have high

bandwidth and low capacitance to pass USB high speed

data signals with minimal distortion.

• D-/D+ Pins Overvoltage Protection for +5.25V and

-5V Fault Voltages

• -3dB Frequency . . . . . . . . . . . . . . . . . . 780MHz

• Low ON Capacitance @ 240MHz. . . . . . . . . 3.3pF

• Low ON-Resistance. . . . . . . . . . . . . . . . . . 6.5Ω

The ISL54224 has OVP circuitry on the D-/D+ com pins

that opens the USB in-line switches when the voltage at

these pins exceeds 3.8V (typ) or goes negative by -0.5V

(typ). 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 transceivers.

• Single Supply Operation (V ) . . . . 2.7V to 5.25V

• 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 digital logic inputs are 1.8V logic compatible when

operated with a 2.7V to 3.6V supply. The ISL54224 has

an open drain OE/ALM pin that can be driven Low to

open all switches and outputs a Low when the OVP

circuitry is activated. It can be used to facilitate proper

bus disconnect and connection when switching between

the USB sources.

Applications*(see page 16)

• MP3 and other Personal Media Players

• Cellular/Mobile Phones

• PDA’s

• Digital Cameras and Camcorders

• USB Switching

The ISL54224 is available in 10 Ld 1.8mmx1.4mm

µTQFN and 10 Ld TDFN packages. It operates over a

temperature range of -40 to +85°C.
