FSA9280A / FSA9288A

USB 2.0 Accessory Detection Switch with 28V FET

Description

Features

The FSA9280A/FSA9288A is a USB 2.0 port accessory

Automatically Detects USB Accessories:

detector and switch with integrated 28V over-voltage

and 1.5A over-current protected FET. Fully controlled

using I²C™, FSA9280A/FSA9288A enables USB ports,

stereo and mono audio headphones/headsets with or

without a microphone, TTY (teletype) converters, wired

remote controller with either one button (send/end) or up

to 12 buttons, USB Charging Downstream Port (CDP),

Dedicated Charging Port (DCP) and ANSI/CEA-936-A

USB Car Kit battery chargers, and UART (Universal

Asynchronous Receiver/Transmitter) data cables to use

a common connector, micro or mini USB 2.0 port.

Factory-mode cables can be detected and switched to

use either the UART or USB data path. The

FSA9280A/FSA9288A can be programmed for manual

switching or automatic switching of data paths based on

accessory detected.

Headsets with Microphone and/or Remote

Headphones with/without Remote

USB Port

USB CDP, DCP, or Car Kit Battery Chargers

Factory-Mode Cables

UART Serial Link

TTY Converter

Automatically Configures Switch Connections with

Independent Override Capability

Low-Power Mode When No Accessory Attached

Integrated 28V Over-Voltage and 1.5A Over-

Current Protection FET on V_BUSfor Fault Isolation

Higher Over-Voltage (8V Typical) Option:

FSA9288A

The architecture uses a simple standard resistor to

ground on the ID pin of the accessory’s micro-B or

micro-A/B connector to detect the accessories.

FSA9280A/FSA9288A has advanced modes for wired

remote control sensing for audio accessories and

streamlined detection for simple factory testing. These

devices are designed to allow audio signals to swing

below ground on the USB port data lines.

Negative-Swing-Capable Audio Channel

Separate Logic/Power Controls for Enhanced

Factory-Mode Operation

20-Lead Ultrathin Molded Leadless Package

(3mm x 4mm x 0.55mm)
