DG2592DN1-T1-GE4

Audio Special Purpose Overview

The DG2592DN1-T1-GE4 is an audio jack detector and pop noise control switch IC manufactured by Vishay Siliconix. It integrates circuits to detect stereo headsets with microphones and send/end buttons. The device operates on a single supply voltage ranging from 1.6 V to 5.5 V, with a maximum quiescent current of 10 μA at VDD = 1.8 V. It features an integrated sense comparator for audio L detection with a threshold of 1.4 V ± 5 %. The MIC bias switch provides a maximum on-resistance of 1.2 Ω. The component is housed in a UTMQFN-10 package measuring 1.4 mm x 1.8 mm x 0.35 mm.

Audio Special Purpose Feature Summary

• Integrated audio jack detection with logic output (DET) indicating headset presence
• Low quiescent current of 10 μA maximum at VDD = 1.8 V
• MIC bias switch with low on-resistance (max 1.2 Ω) for quick discharge
• ESD protection exceeding 8 kV HBM and 15 kV IEC air discharge

Audio Special Purpose Applications

• Cellular phones
• Tablet devices
• Portable media players
• Digital cameras

Audio Special Purpose Procurement Notes

Verify the ordering suffix '1' confirms the UTMQFN-10 package variant with a thickness of 0.35 mm, distinct from the standard miniQFN-10 version. Confirm the reel quantity is 3000 units per datasheet specifications. Ensure compatibility with surface mount assembly processes suitable for ultra-thin packages.

Audio Special Purpose Selection Notes

Select this part when an ultra-thin profile (0.35 mm) is required compared to the standard 0.55 mm miniQFN-10 option. Verify that the operating voltage range of 1.6 V to 5.5 V aligns with the system power rails. Check if the integrated S/E detect functionality is necessary or if the basic detection mode suffices for the application design.

Audio Special Purpose Part Context

This component belongs to the DG2592 family of audio jack detectors. The DG2592DN1-T1-GE4 specifically denotes the UTMQFN-10 package variant. Other variants include the DG2592DN-T1-GE4 which utilizes the thicker miniQFN-10 package. Both share identical electrical characteristics but differ in physical dimensions.

Audio Special Purpose Replacement Considerations

The DG2592DN-T1-GE4 serves as a direct functional substitute, differing only in package height (0.55 mm vs 0.35 mm). No other cross-model substitutes are documented in the provided source material.
