DG2591 www.vishay.com Vishay Siliconix Audio Jack Detector and Pop Noise Control Switch DESCRIPTION FEATURES The DG2591 is an audio jack detector and pop noise control switch IC. • Operates with 1.8 V ± 5 % When there is no ear phone detected, the DG2591 connects the microphone bias line to ground through the MIC pin. The DG2591 also gives a logic HIGH signal to the baseband controller through the OUT pin. • Integrated sense comparator for audio L of 1.4 V ± 5 % threshold The DG2591 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 DG2591 will indicate the presence of the ear phone by pulling OUT low and the MIC switch will turn off. The DG2591 is available ultra small miniQFN6 of 1 mm x 1.2 mm size. • Low quiescent current of 2 μA/max. • 1 Ω/max. MIC bias switch provides a quick discharge and clamping • (Integrated deglitch circuit) • ESD Protected - Human body model > 5 kV - Charged device model > 1 kV - IEC 61000-4-2 air discharge > 15 kV - IEC 61000-4-2 contact discharge > 8 kV • Ultra compact miniQFN6 of 1 mm x 1.2 mm • Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 APPLICATIONS • Cellular phones • Tablet devices • Portable media players • Digital cameras 1.8V To Audio PA Output V+ R1 10K To MIC Bias, 2.4V L_Detect MIC RMIC = 2.2K GND_Detect R2 OUT Ear Jack Detection Output to App Processor Earphone SW2 GND Fig. 1 - Typical Operation Circuit S14-2036-Rev.

It should be compliant with either high or low logic • Negative current injection up to 300 mA Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. S14-2036-Rev.
