FSUSB45 Hi-Speed USB2.0 (480Mbps) Switch with Dedicated Charger Port Detect July 2013 FSUSB45 High-Speed USB2.0 (480Mbps) Switch with Dedicated Charger Port Detect Features Description The FSUSB45 is a bi-directional, low-power, two-port, Low On Capacitance: 7.0 pF Typical High-Speed, USB2.0 switch. Configured as a double- Low On Resistance: 3.9 Typical pole, double-throw (DPDT) switch, it is optimized for switching between two HS (480 Mbps) sources or an Low Power Consumption: 1 A Maximum HS source and a Full-Speed (12 Mbps) source. - 15 A Maximum I over an Expanded Voltage CCT The FSUSB45 is compatible with the requirements of Range (V =1.8 V, V =4.3 V) IN CC USB2.0 and features an extremely low on capacitance Wide -3 db Bandwidth: > 720 MHz (C ) of 7.0 pF. The wide bandwidth of this device ON (720 MHz) exceeds the bandwidth needed to pass the Packaged in: third harmonic, resulting in signals with minimum edge - 10-Lead MicroPak (1.6 x 2.1 mm) and phase distortion. Superior channel-to-channel crosstalk also minimizes interference. - 10-Lead UMLP (1.4 x 1.8 mm) 8 kV ESD Rating, >16 kV Power/GND ESD Rating The FSUSB45 contains special circuitry on the switch I/O pins for applications where the V supply is CC Power-Off Protection on All Ports When V 0 V CC= powered-off (V =0), which allows the device to CC - D+/D- Pins Tolerate up to 5.25 V withstand an over-voltage condition. This device is designed to minimize current consumption even when the control voltage applied to the SEL pin is lower than Applications the supply voltage (V ). This feature is especially CC valuable to mobile applications, such as cell phones, Cell Phone, PDA, Digital Camera, and Notebook allowing for direct interface with the general-purpose LCD Monitor, TV, and Set-Top Box I/Os of the baseband processor. An additional feature is the detection of the 1,1 state on D+/D- to signal an interrupt (INT) to the processor when entering a IMPORTANT NOTE: dedicated charging port mode of operation.
