description
The TISP61060 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 TISP61060
limits voltages that exceed the SLIC supply rail
voltage.

SD6XAE
Terminals K1, K2 and A correspond to the alternative
line designators of T, R and G or A, B and C. The
negative protection voltage is controlled by the voltage,
V
GG,
applied to the G terminal.
The SLIC line driver section is typically powered 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. (see Applications Information).
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.
