TWS Bluetooth earphones ESD EOSProtection plan
1. TWS Bluetooth earphones
TWS（True Wireless Stereo）Bluetooth earphones refer to completely wireless earphones without traditional cables，Usually composed of two independent earphones placed separately in the ears，Provide stereo sound effects。These types of headphones have become increasingly popular in recent years，Because they provide more freedom、More convenient audio experience。
2. TWS Bluetooth earphones requireESD EOSReason for protection plan
abouttwsheadsetwith regard to，To ensure that the equipment is not negatively affected by electrostatic discharge，Improve product reliability and user experience，InternalESDProtective devices are essential or missing。
IfTWSNo headphones availableESDprotectcomponent，There are the following risks：
l absenceESDUnder protection，When headphones are subjected to electrostatic discharge，Causing damage to circuit components。
l Electrostatic discharge may cause interference or damage to the functional modules of headphones，Causing audio output distortion、cannot connect、Control function failure and other issues。
l Data loss：ESDThe event may cause damage or loss of data stored inside the headphones，Including user settings、Music files, etc。
in addition，To cope withTWS The testing standards related to the headphone market include static electricity standards IEC61000-4-2 And surge impact standards IEC61000-4-5，It also needs to be increasedESD Protective devices。
Shanghai Leimao has advanced equipment and a professional team，Can be based onIEC61000-4-2 andIEC61000-4-Provide customers with recommended solutions based on the testing standards of 5 and the anti-static requirements of the product itself，Including providing low capacitance transient voltage suppressors、ESDProtective devices，OVPEqual components，Provide targetedTWSHeadphoneESDandEOSIntegrated protection solutions, etc。

4. TWS Headphone charging compartment ESD&EOS Overall solution
Due to space limitations and reasons for mobility and portability，TWS The headphone protection scheme needs to provide a compact design，Low capacity，Low leakage current，High stability protective devices。The recommended components for Shanghai Leimao's solution are mostly DFN0603，DFN1006 encapsulation，aim atTWSRecommend using a small package at the charging port of the earphonesDFN1006 high-powerESDProtective devices，For the charging compartment Vbus, choiceDFN1610 packaging has certain resistanceESDandEOS performance，And you can choose various voltages according to your needs，For high-frequency signals such as BluetoothantennaRecommend using low capacity small packaging to bring back and scanESD Protective devices，Can better protect the rear stagechip，Targeting the issue of low leakage current，AllESDProtective devices IR <0.1uA。therefore，This plan is very suitableTWS Bluetooth earphones and other wearable products。
