USING TPD4F003 or TPD4S012 for TSU8111 for ESD Prootection

Other Parts Discussed in Thread: TPD4S012, TPD4F003, TSU8111, TPD4S214

Hello


I am designing a device that have USB port for Charging, Data communication and JIG function.

I decide to use TSU8111 as USB switch port, about the ESD protection for this USB Port Switch, if you look on datasheet (pdf file) page 33 (APPLICATION SCHEMATIC), There is 9 components on the schematic between TSU8111 and USB connector, all used for ESD protection, I know that TI also have TPD4F003 (ESD and EMI protection chip) and  TPD4S012 (ESD Protection chip) that are very concise and designed especially for ESD and EMI protections, can you let me know which one you suggest for use with TSU8111?

  • Nader,

    TSU8111 is targeting space limited applications. I recommend TPD4S214 as it is also targeted at space limited applications. Also, it provides full USB port protection. Up to 30V DC on VBUS, +/- 15 kV ESD, an adjustable current limiter up to 2A, and over voltage, under voltage lockouts.

    Regards,
