Hi team,

My customer is looking for a HS switch which has independent Vs pin. Use case is serilize two HS switch for redundancy protection, however if the first swithch turned down and the second switch will lose power and protect function. Could you please recommend one released device or in-development device?

    Hi Sirui,

    Can you please explain what you mean by independent VS pin? All our high side device have dedicated VS pins which is used as both the supply for the device and the supply that is connected to the output. Do you mean an independent VDD pin with which to supply the internals of the device and set references? This is available on some industrial devices and on our TPS2HCS10-Q1 device. 

    Most automotive devices use the Vs pin to power the device.

    Thanks,

    Correct. Customer need the system working like below: Dual switch for redundancy safety requirement, if the first turned down and the second could work at the same time. Could you recommend one industrial device which has this Vdd pin? Product webpage doesn't has this filter.
