TISP61089BSD High Voltage Ringing SLIC Protector
APPLICATIONS INFORMATION
Operation of Ringing SLICs using Multiple Negative Voltage Supply Rails
Figure 4 shows a typical powering arrangement for a multi-supply rail SLIC. V BATL is a lower (smaller) voltage supply than V BATH . With supply
switch S1 in the position shown, the line driver amplifiers are powered between 0 V and V BATL . This mode minimizes the power consumption
for short loop transmission. For long loops and to generate ringing, the driver voltage is increased by operating S1 to connect V BATH . These
conditions are shown in Figure 5.

Figure 5. Driver Supply Voltage Levels
Conventional ringing is typically unbalanced ground or battery backed. To minimize the supply voltage required, most multi-rail SLICs use
balanced ringing as shown in Figure 5. The ringing has d.c., V DCRING , and a.c., V PKRING , components. A 70 V r.m.s. a.c. sinusoidal ring signal
has a peak value, V PKRING , of 99 V. If the d.c. component was 20 V, then the total voltage swing needed would be 99 + 20 = 119 V. There are
internal losses in the SLIC from ground, V SLICG , and the negative supply, V SLICH . The sum of these two losses generally amounts to a total of
10 V. This makes a total, V BATH , supply rail value of 119 + 10 = 129 V.
In some cases a trapezoidal a.c. ring signal is used. This would have a peak to r.m.s ratio (crest factor) of about 1.25, increasing the r.m.s. a.c.
ring level by 13 %. The d.c. ring voltge may be lowered for short loop applications.
