USB transceiver and USB accessory detection switch from Fairchild for mobile design

Fairchild has introduced new USB transceiver, FUSB2500 and USB accessory detection switch, FSA9280A. It is said to bring functional enhancements without adding design complexity or increasing space and power in mobile designs.

The various advantages of micro-USB switch (FSA9280A) and USB transceiver (FUSB2500) as per Fairchild in the mobile space are as follows:

Auto Detection: The FSA9280A can detect every accessory and charger in the market and has a number of "reserved" resistors to accommodate new accessories such as glucometers, e-frames and audio docks. The FUSB2500 has an integrated charger detect that allows detection without additional component count.

Power Savings: The FSA9280A uses advanced sampling methods to reduce power consumption in the standby state and extend battery life. It also provides a negative switch capability in audio applications without consuming power; alternative solutions need a charge pump for this. Both the FSA9280A and FUSB2500 offer a low power down function that puts the device in standby when functions are not in use.

Audio Fidelity: The FSA9280A features low Total Harmonic Distortion (THD) of 0.1 percent to optimize performance.

Protection Functions: The FSA9280A features many built-in protection functions and the FUSB2500 offers high ESD protection, 15kV HBM, exceeding the 2kV standard.

FSA9280A packs both MOSFET and USB IP into one IC.

Price:
FUSB2500UCX costs US$1.00 for 1000 pieces.
FSA9280AUMX costs US$1.00 for 1000 pieces.
