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 DW-16 PACKAGE IS Safety input, output, or supply current RθJA = 86.5 °C/W, VI = 5.5 V, TJ = 150°C, TA = 25°C, see Figure 1 263 mA RθJA = 86.5 °C/W, VI = 3.6 V, TJ = 150°C, TA = 25°C, see Figure 1 401 RθJA = 86.5 °C/W, VI = 2.75 V, TJ = 150°C, TA = 25°C, see Figure 1 525 PS Safety input, output, or total power RθJA = 86.5 °C/W, TJ = 150°C, TA = 25°C, see Figure 2 1445 mW TS Maximum safety temperature 150 °C D-8 PACKAGE IS Safety input, output, or supply current RθJA = 137.7 °C/W, VI = 5.5 V, TJ = 150°C, TA = 25°C, see Figure 3 165 mA RθJA = 137.7 °C/W, VI = 3.6 V, TJ = 150°C, TA = 25°C, see Figure 3 252 RθJA = 137.7 °C/W, VI = 2.75 V, TJ = 150°C, TA = 25°C, see Figure 3 330 PS Safety input, output, or total power RθJA = 137.7 °C/W, TJ = 150°C, TA = 25°C, see Figure 4 908 mW TS Maximum safety temperature 150 °C 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 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. |
