I came across while reading the opto-isolator technique used for electric isolation in embedded systems/ Integrated Circuits design that " Opto-isolator is not recommended for electric isolation in power applications IC's mainly due to it's dV/dt sensitivity". So I would like to know:
1)How dV/dt sensitivity affects isolation?
2)Is dV/dt sensitivity the only reason to avoid optocoupler especially in power application IC/embedded systems?
3)Are there other limitations in optocoupler which compel one to chose other isolation techniques?
Looking forward to your suggestions and guidance. Thanks.
