Description  
G1  
G2  
The TISP9110LDM is a programmable overvoltage protection  
device designed to protect modern dual polarity supply rail  
ringing SLICs (Subscriber Line Interface Circuits) against  
overvoltages on the telephone line. Overvoltages can be caused  
by lightning, a.c. power contact and induction. Four separate  
protection structures are used; two positive and two negative to  
provide optimum protection during Metallic (Differential) and  
Longitudinal (Common Mode) protection conditions in both  
polarities. Dynamic protection performance is specified under  
typical international surge waveforms from Telcordia GR-1089-  
CORE, ITU-T K.44 and YD/T 950.

The TISP9110LDM is programmed by connecting the G1 and G2  
gate terminals to the negative (-V  
) and positive (+V )  
(BAT)  
(BAT)  
SLIC Battery supplies respectively. This creates a protector operating at typically +1.4 V above +V  
(BAT)  
and -1.4 V below -V  
under a.c.  
(BAT)  
power induction and power contact conditions. The protector gate circuitry incorporates 4 separate buffer transistors designed to provide  
independent control for each protection element. The gate buffer transistors minimize supply regulation issues by reducing the gate current  
drawn to around 5 mA, while the high voltage base emitter structures eliminate the need for expensive reverse bias protection gate diodes.  
The TISP9110LDM is rated for common surges contained in regulatory requirements such as ITU-T K.20, K.45, Telcordia GR-1089-CORE,

YD/T 950. By the use of appropriate overcurrent protection devices such as the Bourns Multifuse and Telefuse devices, circuits can be  
designed to comply with modern telecom standards.
