Hi all,
I have a design using the ADG836L mux. The inputs to the mux are connected to a pogo pin assembly that is used in a production environment to program microcontrollers. I am using these multplexor/switches to rout the signals to the device programmer. I am experiencing an issue where the first ADG836L in the chain gets in to a latched condition and starts drawing excessive current. Cycling power temporarily fixes the problem until it happens again.
My initial thought is that there is a static charge built up on the surface that the pogo assembly contacts and that this is causing this fault. I was hoping someone might be able to provide some clarification as to what might be causing this problem and how I might go about preventing it.
