7.7 Safety Limiting Values

Safety limiting intends to prevent 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 absolute-maximum junction temperature specified in the Absolute Maximum

Ratings table. 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

Thermal Information table is that of a device installed in the 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.
