7.8 Safety Limiting Values

Safety limiting intends to minimize potential damage to the isolation barrier upon failure of input or output (I/O) circuitry. A failure of the I/O may 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.
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
IS Safety input, output, or supply current RθJA = 84.6°C/W, TJ = 150°C, TA = 25°C,
VDD1 = VDD2 = 5.5 V, see Figure 2 		268 mA
RθJA = 84.6°C/W, TJ = 150°C, TA = 25°C,
VDD1 = VDD2 = 3.6 V, AMC1311B only, see Figure 2 		410
PS Safety input, output, or total power(1) RθJA = 84.6°C/W, TJ = 150°C, TA = 25°C, see Figure 3 1477 mW
TS Maximum safety temperature 150 °C
(1) Input, output, or the sum of input and output power must not exceed this value.

The maximum safety temperature is the maximum junction temperature specified for the device. 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 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.
