6.6 Safety Limiting Values

Safety limiting 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.
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
IS Safety input, output, or supply current RθJA = 263°C/W, VI = 5.5 V, TJ = 170°C, TA = 25°C, see Figure 9-6 100 mA
RθJA = 263°C/W, VI = 3.6 V, TJ = 170°C, TA = 25°C, see Figure 9-6 153
TS Safety temperature 150 °C
