Description
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(BAT)) and positive (+V(BAT))
SLIC Battery supplies respectively. This creates a protector operating at typically +1.4 V above +V(BAT) and -1.4 V below -V(BAT) under a.c.
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.
