TS3USB3000: what is the OVP threshold for D+/- short protection from VBUS?

Part Number: TS3USB3000
Other Parts Discussed in Thread: TS5USBC402,

 Hello, 

 [8.3.2 Overvoltage Protection When 9-V Short to D+/– Pin]  in the datasheet,  but, we don't have its working threshold in the electrical table. 

what is the OVP threshold for working?   and  what is the hysteresis to get released from the protection?   

  • Hi Dennis,

    TS3USB3000 does not support OVP..TS5USBC402 could fit here and the specs you are looking for are listed in section 6.5 Electrical Characteristics in the datasheet. 

  •  Thanks  Malik, 

     if TS3USB3000 doesn't support OVP,  we do made critical wrong information in the datasheet.  

     would you look at  [8.3.2 Overvoltage Protection When 9-V Short to D+/– Pin] description ?  

     It seems TS3USB3000 and TS5USBC402 look very similar but, need to clarify exact application & use purpose.   Also,  TS3USB3000 features 6.1GHz BW while TS5USBC402 supports 1.2GHz BW.   how can I separate two products for what use purpose? 

  • Hi Dennis,

    Sorry my previous post was incorrect. TS3USB3000 can protect the D+/- pins from voltage 5V to 9V as described in datasheet but there can potentially be relatively large amounts of leakage current in a OVP event (V_D+/- > 5V). I recommend using TS5USBC402 which has a similar OVP threshold but tolerate higher voltages on the D+/- pins (up to 20 V). This device is typically used in Type-C applications. If the customer is not using MHL, Only USB, then TS5USBC402 bandwidth will be more than sufficient.
