Description
The TISP8200M/TISP8201M combination has been designed to protect
dual polarity supply rail monolithic SLICs (Subscriber Line Interface
Circuits) against overvoltages on the telephone line caused by lightning,
a.c. power contact and induction. Protection against negative
overvoltages is given by the TISP8200M. Protection against positive
overvoltages is given by the TISP8201M. Both parts are in 8-pin small-
outline surface mount packages.
The TISP8200M has an array of two buffered P-gate SCRs with a
common anode connection. Each SCR cathode and gate has a separate
terminal connection. The NPN buffer transistors reduce the gate supply
current.
In use, the cathodes of the TISP8200M SCRs are connected to the two
conductors of the POTS line (see applications information). The gates are
connected to the appropriate negative voltage battery feed of the SLIC
driving the line conductor pair. This ensures that the TISP8200M
protection voltage tracks the SLIC negative supply voltage. The anode of
the TISP8200M is connected to the SLIC common.
