STMicroelectronics EVLSTDRIVEG212 Evaluation Board
STMicroelectronics EVLSTDRIVEG212 Evaluation Board is easy to use, as well as quick and suitable for evaluating the characteristics of the STDRIVEG212 driving two 2.2mΩ (typical), 100V emode GaN switches in a half-bridge configuration. The STDRIVEG212 is a 220V high-speed half-bridge gate driver optimized for 5V driving enhanced-mode GaN HEMTs. It features separated high-current sink/source gate driving pins, integrated LDOs, undervoltage, bootstrap diode, high-side fast startup, overtemperature, fault/shutdown pins, and standby to fully support hard-switching topologies in a 4mm x 5mm QFN package. The EVLSTDRIVEG212 board is also suitable for evaluating the STDRIVEG612 features.
It provides an onboard programmable deadtime generator and a 3.3V linear voltage regulator to supply external logic such as microcontrollers. Spare footprints are also included to allow for customization of the board for the final application, such as separate LIN and HIN input signals or a single PWM signal. The STMicroelectronics EVLSTDRIVEG212 is 56mm x 79mm in size, with four layers, weighing 1.5oz, and mounted on a FR-4 PCB, resulting in an overall 19°C/W Rth(J-A) (equivalent to 38°C/W for each GaN) in still air without a heatsink, suitable for evaluating high-power applications.
