Hello all,
for specific timing tests of output driver diagnostics, I'd need some kind of very fast switching (solid state) relay with low on-resistance (definitely below 0.1Ohm).
In a nutshell, I'd like to apply e.g. a 100 to 10 µs short circuit to ground, open load or short circuit to power condition on low side driver outputs and also on high side driver outputs. Since the outputs have full diagnostic capabilities, they will switch off quickly in case of critical overcurrent (within a a few microseconds), but for this short time, the short circuit current will be pretty high (let's say like 30A or even more). Also I will place this on couple of points in the circuit as well.
While I think I could probably use an N-channel logic level FET controlled by a signal generator with an according offset/amplitude, I'd like to use a more solid solution for a couple or reason. E.g. I'd like to control the switch with a 0V/5V signal without the need to adjust the offset for the specific test case. And honestly there is no time to design and test a circuit. I'd need a solid product that's just working and that's easily available. Price is not so much of a problem. This is neither for private stuff nor for mass production.
So are there faster DC solid state relays available?
Thanks,
Nenad
