Safety Limiting Values

Safety limiting intends to minimize potential damage to the isolation barrier uponfailure of input or output circuitry.
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
IS Safety input, output, or supply current(1) RθJA = 68.5 °C/W, VI = 5.5 V, TJ = 150 °C, TA = 25 °C, See Figure 8-1 332 mA
RθJA = 68.5 °C/W, VI = 3.6 V, TJ = 150 °C, TA = 25 °C, See Figure 8-1 507
PS Safety input, output, or total power(1) RθJA = 68.5 °C/W, TJ = 150 °C, TA = 25 °C, See Figure 8-2 1826 mA
TS Safety temperature(1) 150
The maximum safety temperature,TS, has the same value as the maximum junction temperature,TJ, specified for the device. The IS andPS parameters represent the safety current and safety power respectively.The maximum limits of IS and PS should not beexceeded. 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 forleaded 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) isthe maximum allowed junction temperature.

PS = IS × VI, whereVI is the maximum input voltage.
