I used PSM712 and PSD12C with 2 resettable fuses(100mA,60V) at output pins(A,B) of RS485 driver IC(ADM485) but these comabination can not protect
driver IC from failure when high voltage (for example 24V) is applied to A ,B and GND lines.
Please help me to design a circuit that is reliable when high voltage is applied to it by mistake in wiring.
