Hi-Speed USB and Audio Switches with Negative Signal
Capability and High-Voltage-Tolerable VBUS Detection
________________________________________________________________
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.
