The useful range of a driver is greatly affected by the drive-power requirements of the load and the thermal characteristics of the package. For a gate driver to be useful over a particular temperature range, the package must allow for efficient removal of the heat produced while keeping the junction temperature within rated limits. The thermal metrics for the driver package are listed in Thermal Information section. For detailed information regarding the table, refer to the Application Note from Texas Instruments entitled Semiconductor and IC Package Thermal Metrics (SPRA953). The UCC27311A device is offered in a 10-pin VSON package (DRC).
