The useful range of a driver is greatly affected by the drive power requirements of the load and the thermal characteristics of the package. In order for a gate driver to be useful over a particular temperature range the package must allow for the efficient removal of the heat produced while keeping the junction temperature within rated limits. The thermal metrics for the driver package is summarized in the ‘Thermal Information’ section of the datasheet. For detailed information regarding the thermal information table, please refer to Application Note from Texas Instruments entitled “IC Package Thermal Metrics” (SPRA953A).
