112 / 242 page  7.9 Thermal Resistance Characteristics This section provides the thermal resistance characteristics used on this device. For reliability and operability concerns, the maximum junction temperature of the device has to be at or below the TJ value identified in Recommended Operating Conditions. 7.9.1 Thermal Resistance Characteristics Table 7-2. ALV Package Thermal Resistance Characteristics It is recommended to perform thermal simulations at the system level with the worst case device power consumption. NO.
