STMicroelectronics EVLSTDRIVEG610Q Evaluation Board
STMicroelectronics EVLSTDRIVEG610Q Evaluation Board is based on the STDRIVEG610 high-speed, half-bridge gate driver, which is optimized to drive high-voltage, enhanced-mode, GaN HEMTs. The STDRIVEG610 offers separated high current sink/source gate driving pins, integrated LDOs, bootstrap diode, undervoltage, high-side fast startup, overtemperature, fault and shutdown pins, and standby to support hard switching topologies in a 4mm x 5mm QFN package.
The STMicroelectronics EVLSTDRIVEG610Q board is easy to use and adaptable for evaluating the features of the STDRIVEG610 driving the SGT120R65AL 75mΩ typ., 650V E-Mode GaN switches in the 5mm x 6mm QFN package. The device supplies an onboard programmable deadtime generator and a 3.3V linear voltage regulator to supply external logic like microcontrollers. Spare footprints are also incorporated to customize the board for the final application, such as separate LIN and HIN input signals or a single PWM signal.
The EVLSTDRIVEG610Q is 56mm x 70mm wide, two layers, 1.5Oz, FR-4 PCB, resulting in an overall 24°C/W Rth(J‑A) of 24°C/W (equivalent to 48°C/W for each GaN) in still air to evaluate high-power applications.
