In the negative polarity, the PBL 3762A RING or TIP voltage must not exceed V
BAT
- 70. Continuously the
PBL 3762A can withstand a V
BAT
of -70 V and this implies a maximum peak voltage of -140 V. Figure 15 is
drawn for a V
BAT
of -50 V and so that the peak voltage becomes -120 V.
For 250 ns, the PBL 3762A will be able to withstand a voltage between V
BAT
-40V and V
BAT
-70 V or -90 V
and -120 V in this case. For 1 μs, the PBL 3796 will be able to withstand a voltage between V
BAT
-20V and
V
BAT
-40 V or -70 V and -90 V in this case. For 10 ms, the PBL 3796 will be able to withstand a voltage
between V
BAT
and V
BAT
-20 V or -50 V and -70 V in this case. By adding a series feed diode in the battery
feed the d.c. and 10 ms voltage withstands increase to -70 V, independent of the actual V
BAT
value.To protect
against negative overvoltage, the TISPPBL2S negative limiting voltage must be equal to or less than these
voltage values during the specified time periods.
The following table lists the protection requirements of three selections from different SLIC families. Two, the
PBL 3796 and the PBL 3762A, specify voltage withstand. The PBL 3796 specifies the negative voltages in
absolute terms and the PBL 3762A specifies the negative voltages in terms of voltage relative to the battery
supply voltage, V
BAT
.
Tertiary protection is incorporated in the PBL 386 20/1 SLIC and the withstand is specified in terms of current
into this protection. This type of SLIC also has more time periods specified for the current withstand values.
To co-ordinate the SLIC external secondary protection (TISPPBL2S) and the internal tertiary protection, a
series resistor, R
P
, is required between the two. The tertiary protection will develop about 1 V and the
withstand current through resistor R
P
will also develop a voltage. The sum of these voltages will determine the
required limiting voltage level of the TISPPBL2S. A suitable value for R
P
is 2
.
The negative limiting voltage of the TISPPBL2S is defined as a 1 μs, -20 V pulse below the battery voltage
(Figure 2). This value does not exceed any of the voltage withstand levels listed in the SLIC withstand table. In
the positive polarity the TISPBL2S limits the maximum voltage to 8 V in a 1 μs period and between 1 V and
5 V for a 10 ms period. These values do not exceed the values listed in the SLIC withstand table.
