The MAX14585/MAX14585A high-ESD-protected double-pole/double-throw (DPDT) switches multiplex Hi-Speed (480Mbps) USB and analog signals such as AC-coupled audio or video. These devices combine the low on-capacitance (CON) and low on-resistance (RON) necessary for high-performance switching applications in portable electronics and include an internal negative supply to pass audio signals that swing below ground down to -1.8V. The devices also handle USB low-/full-speed signaling and operate from a 2.7V to 5.5V supply.

The devices feature a VBUS detection input (VB) that can handle voltage up to 28V to automatically switch to the USB signal path upon detection of a valid VBUS signal (VB > VVBDET). In a dead battery situation, the voltage on VB can supply power to the part if VB is greater than 4.5V. The MAX14585 features internal shunt resistors on the audio path to reduce clicks and pops heard at the output.

The MAX14585/MAX14585A are available in a space-saving, 10-pin, 1.4mm x 1.8mm UTQFN package and operate over the -40°C to +85°C temperature range.

Product Detail

The MAX14585 evaluation kit (EV kit) provides a proven design to evaluate the MAX14585 high-ESD-protected double-pole/double-throw (DPDT) switch. The EV kit is designed to demonstrate the MAX14585 used in USB 2.0 Hi-Speed-compliant switching applications. The EV kit circuit routes a multiplexed signal from one USB port to another USB port and routes an audio signal to a headphone jack.

The EV kit PCB comes with a MAX14585EVB+ installed and can also be used to evaluate the MAX14585A.

Applications

  • Cell Phones
  • PDAs and Handheld Devices
  • Tablet PCs
