DEVICE TYPE
The TISP61511D and TISP61512P are dual
forward-conducting buffered p-gate overvoltage
protectors.
monolithic Subscriber Line Interface Circuits,
SLICs, against overvoltages on the telephone
line caused by lightning, ac power contact and
induction. The TISP61511D and TISP61512P
limit voltages that exceed the SLIC supply rail
voltage.
The SLIC line driver section is typically powered
WAVE SHAPE
from 0 V (ground) and a negative voltage in the region of -10 V to -70 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 on-state condition. As the current subsides the high holding
current of the crowbar prevents d.c. latchup.
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 buffered gate design reduces the
loading on the SLIC supply during overvoltages caused by power cross and induction.
