TISP4xxxH3/M3BJ Series for LCAS Protection
LCAS Switch Ratings
When a switch is in the off state, the maximum withstand voltage may be set by the switch itself or by the control line to the switch. At 25 ° C,
the switch terminal to ground voltage rating for all the switches is ± 320 V. Switches SW1 to SW3 are bidirectional MOS types and can
withstand ± 320 V between terminals. Switch SW4 is a bidirectional thyristor which is rated at ± 465 V between terminals.
Overcurrents as well as overvoltages occur on telephone lines. In the on state, the thyristor switch, SW4, is capable of withstanding high levels
of current overload. For currents above about 200 mA, the MOS switches, SW1 to SW3, will go into a current limited condition. This will cause
the voltage to rise across the switch and large amounts of power to be developed. In the longer term, this power loss increases the overall chip
temperature. When the temperature exceeds about 125 ° C, thermal shutdown occurs and the switches are set to the off state. Without power
loss, the LCAS will cool. Eventually, the thermal trip will reset, setting the switches back in the high power loss condition again. The cycle of
temperature increase, thermal shutdown, temperature decrease and switch re-activation will continue until the overcurrent ceases.

Figure 13. LCAS Shown with Switch Breakdown Limits
Equivalent Circuit
Figure 13 shows the LCAS switch voltage ratings as breakdown diodes, which must not be allowed to conduct. Each switch has three diodes;
one between poles and the other two from each pole to ground. At 25 ° C, switches SW1 through to SW3 have breakdown diode voltages of
± 320 V. Switch SW4 has breakdown diode voltage values of ± 465 V for the one between poles and ± 320 V for the two diodes connected to
ground. Note that only protection to ground is required, as in the limit, the inter-switch voltage limitation of ± 640 V is the same as the switch to
ground limitation of +320 V and -320 V in both polarities.
