(1)

The maximum safety temperature, TS, has the same value as the maximum junction temperature, TJ, specified for the device. The IS

and PS parameters represent the safety current and safety power, respectively. Do not exceed the maximum limits of IS and PS. These

limits vary with the ambient temperature, TA.

The junction-to-air thermal resistance, RθJA, in the Thermal Information table is that of a device installed on a high-K test board for

leaded surface-mount packages. Use these equations to calculate the value for each parameter:

TJ = TA + RθJA × P, where P is the power dissipated in the device.

TJ(max) = TS = TA + RθJA × PS, where TJ(max) is the maximum junction temperature.

PS = IS × VDDmax, where VDDmax is the maximum low-side voltage.

6.8 Safety Limiting Values

Safety limiting

(1) intends to minimize potential damage to the isolation barrier upon failure of input or output circuitry. A failure

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

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