Product overview
Description
The STDRIVEG611 is a high-speed, half-bridge gate driver optimized to drive high-voltage, enhanced mode, GaN HEMTs.
It features separated high current sink/source gate driving pins, integrated LDOs, undervoltage, bootstrap diode, overcurrent protection with SmartShutDown, overtemperature, fault and shutdown pins, and standby to fully support hard switching topologies in a 4x5mm QFN package.
The EVLSTDRIVEG611 board is easy to use and quick and adapt for evaluating the characteristics of the STDRIVEG611 driving the SGT120R65AL 75 mΩ typ., 650 V E-Mode GaN switches in the 5x6 mm QFN package.
It provides an onboard programmable deadtime generator and a 3.3 V linear voltage regulator to supply external logic like microcontrollers.
Spare footprints are also included to allow customizing the board for the final application, such as separate LIN and HIN input signals or single PWM signal.
The EVLSTDRIVEG611 is 56 x 70 mm wide, 2 layers, 2 Oz, FR-4 PCB, resulting in 23 °C/W Rth(J‑A) (equivalent to 46 °C/W for each GaN) in still air to evaluate high power applications.
