STMicroelectronics EVLSTDRIVEG611 Gate Driver Evaluation Board
STMicroelectronics EVLSTDRIVEG611 Gate Driver Evaluation Board features the STDRIVEG611, a high-speed, half-bridge gate driver optimized to drive high-voltage, enhanced mode, GaN HEMTs. It fully supports hard switching topologies in a 4x5mm QFN package with features of separated high current sink/source gate driving pins, integrated LDOs, undervoltage, bootstrap diode, overcurrent protection with SmartShutDown, overtemperature, fault and shutdown pins, and standby.
The EVLSTDRIVEG611 board is easy to use and quickly adapts for evaluating the characteristics of the STDRIVEG611 driving the SGT120R65AL 75mΩ (typ.), 650V EMode GaN switches in the 5mm x 6mm QFN package. It provides an onboard programmable deadtime generator and a 3.3V linear voltage regulator to supply external logic like microcontrollers. Spare footprints, such as separate LIN and HIN input signals or a single PWM signal, are also included to customize the board for the final application.
The STMicroelectronics EVLSTDRIVEG611 is a 56mm x 70mm wide, two-layer, 2 Oz, FR-4 PCB that results in 23°C/W Rth(J‑A) (equivalent to 46°C/W for each GaN) in still air, which is ideal for evaluating high-power applications.
