High-Speed USB 2.0 (480Mbps) DPST Switch with Overvoltage Protection (OVP)

and Dedicated Charger Port Detection

The ISL54226 is a single supply, dual SPST (Single Pole/Single

Features

Throw) switch that is configured as a DPST. It can operate from a

• High-speed (480Mbps) and full-speed (12Mbps) signaling

capability per USB 2.0

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)

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.

• OE/ALM pin to open all switches and indicate overvoltage

fault condition

• Charger interrupt indicator output

• Power OFF protection

The ISL54226 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.

• COM pins overvoltage protection for +5.25V and -5V fault

voltages

• -3dB frequency . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 790MHz

• Low ON capacitance @ 240MHz. . . . . . . . . . . . . . . . . . . . . 2pF

• Low ON-resistance . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3.5Ω

The OE/ALM logic pin is an open drain input/output that can

be driven to open the switches or monitored to tell when the

part is in an overvoltage state.

• Single supply operation (V ). . . . . . . . . . . . . . . 2.7V to 5.25V

• Available in µTQFN and TDFN packages

• Pb-Free (RoHS compliant)

The part has an interrupt (INT) output pin to indicate a 1 to 1

(high/high) state on the COM lines to inform the µprocessor

when entering a dedicated charging port mode of operation.

• Compliant with USB 2.0 short circuit and overvoltage

requirements without additional external components

The ISL54226 is available in 8 Ld 1.2mmx1.4mm µTQFN and

8 Ld 2mmx2mm TDFN packages. It operates over a

temperature range of -40 to +85°C.

Applications

• MP3 and other personal media players

• Cellular/mobile phones, PDA’s

• Digital cameras and camcorders

• USB switching
