6.8 Safety Limiting Values

Safety limiting intends to minimize potential damage to the isolation barrier upon failure of input or output circuitry. A failure

of the I/O can allow low resistance to ground or the supply and, without current limiting, dissipate sufficient power to overheat

the die and damage the isolation barrier, potentially leading to secondary system failures.

The safety-limiting constraint is the maximum junction temperature specified in the data sheet. The power

dissipation and junction-to-air thermal impedance of the device installed in the application hardware determines

the junction temperature. The assumed junction-to-air thermal resistance in the Section 6.4 table is that of a

device installed on a high-K test board for leaded surface-mount packages. The power is the recommended

maximum input voltage times the current. The junction temperature is then the ambient temperature plus the

power times the junction-to-air thermal resistance.
