voltage would be 140((25+25)/10+15) = 2800 V. Another limitation is long term power cross. The long term
power cross capability of the TISP83121D is 3 A peak or 2.1 A rms. If the line conductor overcurrent
protection was given by a PTC resistor which switched at 0.2 A, the maximum number of conductors
becomes 2.1/0.2 = 10 or 5 lines.
battery supply impedance
In many designs, the battery supply voltages are generated by switching mode power supplies. This type of
power supply cannot be charged like a battery. Feeding a charging current to a switching mode power supply
will usually cause the supply to stop switching and the voltage to rise. The gate current of the TISP83121D is
a charging current for the supply. To avoid the supply voltage from rising and damaging the connected SLICs,
an avalanche diode voltage clamp can be connected across the supply (Figure 3. (A)).
Another approach is to reduce the gate charging current for the supply by a transistor buffer (Figure 3. (B)). If
the transistor gain was 50, a 200 mA gate current would be reduced to a supply charging current of
200/50 = 4 mA In both cases, the dissipation in the control devices can be substantial and power capability
needs to be taken into account in device selection.
