Asking for the recommendation on the reset IC recommendation

Other Parts Discussed in Thread: TPS3710

Hi Team,

Customer is looking the power off reset solution.

 

Would you please recommend the proper solution for this?

 

the customer system design problem is that ch2 and ch3 change from high to low at the same time.

so we are thinking about how to detect Channel 1 level to earlier turn off ch3 signal than Ch2 6ms. do you thin is  that possible if ch1 level less than 10V, then the reset IC can send the low signal to Ch3 and keep always low.

the CH3 high to low need to earlier than Ch2 high to low earlier 6ms.

 

 

BR,

SHH

    SHH,

    This looks like something we can definitely achieve with a voltage supervisor (reset IC). I suggest taking a look at the TPS3710, which can support up to 18 V. You can set the threshold with resistors on the input. The device is also a voltage detector, so should reset instantly and provide you the 6 ms cushion.

    Thanks,
    Abhinav.
