FSA9285UCX

Analog Switches - Special Purpose Overview

The FSA9285UCX is a USB multimedia switch IC manufactured by onsemi, formerly Fairchild Semiconductor. It features a 1 x 3:1 configuration designed for automatic detection and switching between USB host and device connections. The component operates within a supply voltage range of 2.7 V to 4.4 V and supports data rates up to 480 Mbps. Key electrical parameters include a maximum on-resistance of 10 Ohms, with both turn-on and turn-off times limited to 300 ns. It functions reliably across an operating temperature range from -40°C to +85°C and is housed in a WLCSP-20 package.

Analog Switches - Special Purpose Feature Summary

• Integrates automatic detection logic to manage USB host/device connection states without external control.

Analog Switches - Special Purpose Applications

• USB multimedia peripheral switching
• Portable electronic devices requiring USB connectivity management

Analog Switches - Special Purpose Procurement Notes

Verify the current lifecycle status as the part may be End-of-Life (EOL). Confirm RoHS compliance details through official datasheets or manufacturer notifications. Check for authorized distribution channels since availability varies by region. Ensure the WLCSP-20 package compatibility with your PCB design constraints before ordering.

Analog Switches - Special Purpose Selection Notes

Select this component when a single-channel, three-port USB multiplexer with auto-detection is required. Verify that the 10 Ohm on-resistance meets signal integrity requirements for your specific USB application. Ensure the 2.7 V to 4.4 V supply voltage aligns with your system power rails. Consider the WLCSP-20 footprint during layout planning.

Analog Switches - Special Purpose Part Context

This component belongs to the FSA9285A series of USB switches. It is produced by onsemi, which acquired Fairchild Semiconductor's operations. The part serves as a specialized interface solution for managing USB connections in compact consumer electronics, replacing discrete switching components with an integrated IC approach.

Analog Switches - Special Purpose Replacement Considerations
