ISL54206A

MP3/USB 2.0 High Speed Switch with Negative Signal Handling ISL54206A The Intersil ISL54206A dual SPDT (Single Pole/Double Throw) switches combine low distortion audio and accurate USB 2.0 high speed data (480Mbps) signal switching in the same low voltage device. When operated with a 2.7V to 3.6V single supply, these analog switches allow audio signal swings below-ground, allowing the use of a common USB and audio headphone connector in Personal Media Players and other portable battery powered devices. The ISL54206A logic control pins are 1.8V compatible, which allows for control via a standard µcontroller. With a VDD voltage in the range of 2.7V to 3.6V, the IN pin voltage can exceed the VDD rail allowing for the USB 5V VBUS voltage from a computer to directly drive the IN pin to switch between the audio and USB signal sources in the portable device. The part has an audio enable control pin to open all the switches and put the part in a low power state. The ISL54206A is available in a small 10 Ld 2.1mmx1.6mm ultra-thin µTQFN package and a 10 Ld 3mmx3mm TDFN package. It operates over a temperature range of -40°C to +85°C. ISL54206A Features • High Speed (480Mbps) and Full Speed (12Mbps) Signaling Capability per USB 2.0 • Low Distortion Negative Signal Capability • Control Pin to Open all Switches and Enter Low Power State • Low Distortion Headphone Audio Signals - THD+N at 20mW into 32Ω Load. . . . . . . 7kV Machine Model . . . . . . . . . . . . . . . . . . . . . . . . . . >400V Charged Device Model . . . . . . . . . . . . . . . . . . . . . >1.4kV Latch-up Tested per JEDEC; Class II Level A . . . . . . at 85°C Thermal Information Thermal Resistance (Typical) θJA (°C/W) θJC (°C/W) 10 Ld µTQFN (Notes 7, 8) . . . . . . . 145 90 10 Ld TDFN (Notes 9, 10) . . . . . . . 55 16 Maximum Junction Temperature (Plastic Package). . +150°C Maximum Storage Temperature Range . . . -65°C to +150°C Pb-Free Reflow Profile . . . . . . . . . . . . . . . . . .see link below http://www.intersil.com/pbfree/Pb-FreeReflow.asp Operating Conditions Temperature Range . . . . . . . . . . . . . . . . . . -40°C to +85°C CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time.

Limit current to maximum current ratings. 7. θJA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details. 8. For θJC, the “case temp” location is taken at the package top center. 9. θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech Brief TB379. 10. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside.

Flatness is defined as the difference between maximum and minimum value of ON-resistance over the specified analog signal range. 14. RON matching between channels is calculated by subtracting the channel with the highest max rON value from the channel with lowest max RON value, between L and R or between D+ and D-. 15.
