Description
The TISP6L7591 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 TISP6L7591 limits voltages that exceed the SLIC
supply rail voltage.
The SLIC line driver section is typically powered from 0 V (ground)
and a negative voltage, V
, in the region of -20 V to -80 V. The
protector gate is connected to this negative supply. This
references the protection (clipping) voltage to the negative supply
voltage. The negative protection voltage will then track the
negative supply voltage and the overvoltage stress on the SLIC is
minimized.

Note: Pins 1 and 4 must always be connected to the protection
resistors shown in Figures 2 and 3 (Line Feed Circuitry).
The SLIC can be connected either to the protected
outputs (pins 5 and 8) or to the inputs (pins 1 and 4).
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 switch into a low voltage on-state
condition. As the overvoltage subsides the high holding current of TISP6L7591 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 TISP6L7591 is available in 8-pin plastic small-outline surface mount package.
