description  
The TISPPBL2S is a dual forward-conducting buffered p-gate overvoltage protector. It is designed to protect  
the Ericsson Components PBL 3xxx family of SLICs (Subscriber Line Interface Circuits) against overvoltages  
on the telephone line caused by lightning, a.c. power contact and induction. The TISPPBL2S limits voltages  
that exceed the SLIC supply rail levels.  
The SLIC line driver section is typically powered from 0 V (ground) and a negative voltage in the region of  
-10 V to -85 V. The protector gate is connected to this negative supply. This references the protection  
(clipping) voltage to the negative supply voltage. As the protection voltage will track the negative supply  
voltage the overvoltage stress on the SLIC is minimised.  
Positive overvoltages are clipped to ground by diode forward conduction. Negative overvoltages are initially  
clipped close to the SLIC negative supply rail value. If sufficient current is available from the overvoltage, then  
the protector will crowbar into a low voltage ground referenced on-state condition. As the overvoltage
