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 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.

IS Safety input, output, or supply current (1) RθJA =146.1°C/W, VI = 5.5 V, TJ = 150°C, TA = 25°C, see Figure 6-3 156 mA
RθJA = 146.1°C/W, VI = 3.6 V, TJ = 150°C, TA = 25°C, see Figure 6-3 238
RθJA = 146.1°C/W, VI = 2.75 V, TJ = 150°C, TA = 25°C, see Figure 6-3 311
PS Safety input, output, or total power (1) RθJA = 146.1°C/W, TJ = 150°C, TA = 25°C, see Figure 6-4 856 mW
TS Maximum safety temperature (1) 150 °C
(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. The maximum limits of IS and PS should not be exceeded. These limits vary with the ambient temperature, TA. 

The junction-to-air thermal resistance, RθJA, in the 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 allowed junction temperature.
PS = IS × VI, where VI is the maximum input voltage.
