voltage based protection

This question is not answered

Hello,

I am working on a circuit which has high-voltage (~600V) and low-voltage ICs. The IC is powered by a 15 V battery. I am concerned if the IC fails/breaks, my battery could be exposed to the 600V. Does anyone know of a voltage-based protection element? I am envisioning something like a fuse which break when it sees an overvoltage, rather than an over-current.

Any help, comments, or suggestions would be welcome.

Thanks!

    one solution could be, since you have a fuse, to insert an overvoltage crowbar circuit (there are  many simple implementations, made by discretes).

    it basically apply a low Z at the input as the programmed threshold is crossed-over, causing the fuse to blow.
