The TPS7H60x5 series of radiation-hardness-assured (RHA) gallium nitride (GaN) field effect transistor (FET) gate drivers is designed for high frequency, high efficiency, and high current applications. The series consists of the TPS7H6005 (200V rating), TPS7H6015 (60V rating), and the TPS7H6025 (22V rating). Each of these devices has a 56-pin HTSSOP plastic package, and availability in both the QMLP and Space Enhanced Plastic (SEP) grades. The drivers feature adjustable dead time capability, small 30ns propagation delay and 5.5ns high-side and low-side matching. These parts also include internal high-side and low-side LDOs which ensure a drive voltage of 5V regardless of supply voltage. The TPS7H60x5 drivers all have split-gate outputs, providing flexibility to adjust the turn-on and turn-off strength of the outputs independently.
The TPS7H60x5 drivers feature two control input modes: independent input mode (IIM) and PWM mode. In IIM each of the outputs is controlled by a dedicated input. In PWM mode, two complementary outputs signals are generated from a single input and the user can adjust the dead time for each edge.
The gate drivers also offer user configurable input interlock in independent input mode as anti-shoot through protection. Input interlock disallows turn-on of both outputs when both inputs are on simultaneously. The user has the option to enable or disable this protection in independent input mode, which allows the driver to be used in a number of different converter configurations. The drivers can also be utilized for both half-bridge and dual-low side converter applications.

The TPS7H6005 evaluation module demonstrates operating of the TPS7H6005-SEP gate driver. By default, the evaluation module is set up to run with the PWM mode of TPS7H60XX-SP, which accepts an input of one switching signal and internally generates a complementary signal. This can be changed to the (...)
