In this application note are described different ways to protect L3000N/L30XX SLIC KITs.
The L3000N/L30XX are, COMPARED TO STANDARD SOLUTIONS, more complex to protect because the positive battery can be either GND or VB+ (typ. + 72V) depending on the SLIC operating mode. In the following three protection solutions for the L3000N/L30XX KITs are described.
The first solution is based on programmable transient suppressor L3121; and this is the most complete one: another simpler solution, based on standard transient suppressor like LS5120 or TRISIL is proposed. Finally a way to use only one transient suppressor for more subscribers is described.
