DG2592 www.vishay.com Vishay Siliconix Audio Jack Detector with Send / End Detect DESCRIPTION FEATURES The DG2592 is an audio jack detector and pop noise control Wide operating voltage range: 1.6 V to 5.5 V switch IC. It integrates the circuits necessary to detect the Low quiescent current of 10 A, max. at presence of a stereo headset with a microphone and send / V = 1.8 V DD end control button. Integrated sense comparator for audio L of When there is no ear phone detected, the DG2592 connects 1.4 V 5 % threshold the microphone bias line to ground through the MIC pin. The 1.2 /max. MIC bias switch provides quick discharge and DG2592 also gives a logic high signal to the baseband clamping controller through the DET pin. ESD Protected The DG2592 senses the DC levels at both L Detect and - Human body model > 8 kV GND Detect. When an ear phone is plugged in, the voltage - Charged device model > 2 kV at both pins will go low. The DG2592 will indicate the - IEC 61000-4-2 air discharge > 15 kV presence of the ear phone by pulling DET low and the MIC - IEC 61000-4-2 contact discharge > 8 kV switch will turn off. Ultra thin and compact miniQFN10 and UTDFN10 The DG2592 is available in small miniQFN10 of Material categorization: for definitions of compliance 1.4 mm x 1.8 mm x 0.55 mm and ultra thin UTMQFN10 of please see www.vishay.com/doc 99912 0.35 mm thickness.
