The TISP61089 is a dual forward-conducting
buffered p-gate overvoltage protector. It is
designed to protect monolithic SLICs (Subscriber
Line Interface Circuits) against overvoltages on
the telephone line caused by lightning, a.c.
power contact and induction. The TISP61089 limits voltages that exceed the SLIC supply rail voltage. The
TISP61089 parameters are specified to allow equipment compliance with Bellcore GR-1089-CORE, Issue 1.
The SLIC line driver section is typically powered from 0 V (ground) and a negative voltage in the region of
-10 V to -75 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 then 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

... These monolithic protection devices are fabricated in ion-implanted planar vertical power structures for high reliability and in normal system operation they are virtually transparent. The TISP61089 buffered gate design reduces the loading on the SLIC supply during overvoltages caused by power cross and induction. The TISP61089 is available in 8-pin plastic small-outline surface mount package and 8-pin plastic dual-in-line package ...

... Figures 4. and 5. show how the TISP61089 limits negative and positive overvoltages. Positive overvoltages (Figure 5) are clipped by the antiparallel diodes in the TISP61089 and the resulting current is diverted to ground. Negative overvoltages (Figure 4.) are initially clipped close to the SLIC negative supply rail value (V ) ...

... To meet ‘1089, the overcurrent protection must be coordinated with the requirements of sections 4.5.7, 4.5.8, 4.5.9, 4.5.12, 4.5.13, 4.5.15 and the TISP61089. The overcurrent protection must not fail in the first level tests of sections 4.5.7, 4.5.9 and 4.5.12.
