LIFE EXPECTANCY vs WORKING VOLTAGE Figure 4. Life Expectancy vs Working Voltage IEC SAFETY LIMITING VALUES Safety limiting intends to prevent 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 qJA = 212°C/W, VI = 5.25 V, TJ = 150°C, TA = 25°C 112 Safety input, output, or supply IS mA current qJA = 212°C/W, VI = 3.45 V, TJ = 150°C, TA = 25°C 171 TS Maximum case temperature 150 °C The safety-limiting constraint is the absolute-maximum junction temperature specified in the Absolute Maximum Ratings table. 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 Characteristics table is that of a device installed in the JESD51-3, Low-Effective-Thermal-Conductivity Test Board for Leaded Surface-Mount Packages and is conservative. 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. 10 Submit Documentation Feedback Copyright © 2009–2010, Texas Instruments Incorporated Product Folder Link(s): ISO7420 ISO7420M ISO7421 ISO7421M |
