DESCRIPTION

The DG2592 is an audio jack detector and pop noise control

switch IC. It integrates the circuits necessary to detect the

presence of a stereo headset with a microphone and send /

end control button.

When there is no ear phone detected, the DG2592 connects

the microphone bias line to ground through the MIC pin. The

DG2592 also gives a logic high signal to the baseband

controller through the DET pin.

The DG2592 senses the DC levels at both L_Detect and

GND_Detect. When an ear phone is plugged in, the voltage

at both pins will go low. The DG2592 will indicate the

presence of the ear phone by pulling DET low and the MIC

switch will turn off.

The DG2592 is available in small miniQFN10 of

1.4 mm x 1.8 mm x 0.55 mm and ultra thin UTMQFN10 of

0.35 mm thickness.
