Break Before Make Stereo Jack Switches

Ground FET Switches ( <100mΩ)

DESCRIPTION

The TS3A225E is an audio headset switch device.

The device detects the presence of an analog

microphone and switches

microphone pin between different connectors in an

audio stereo jack. The microphone connection in a

stereo connector can be swapped with the ground

connection depending on manufacturer. When the

TAS3A225E detects a certain configuration, the

device automatically connects the microphone line to

the appropriate pin. The device also reports the

presence of an analog microphone on an audio

stereo jack.

Autonomous Detection of GND and MIC

Connections

Detection Triggered by I²C or External Trigger

•

system analog

•

HDA Compatible MIC Present Indicator

1.8V Compatible I²C Switch Control

ESD Performance Tested Per JESD 22:

–

2000-V Human-Body Model (A114-B, Class

II)

–

500-V Charged-Device Model (C101)

•

ESD Performance (SLEEVE, RING2, TIP)

±8-kV Contact Discharge (IEC 61000-4-2)

In some systems, it is desirable to connect the stereo

jack pin to ground. The TS3A225E provides two

internal low resistance (<100mΩ) FET switches for

ground shorting.
