Using the ADuM4136 Isolated Gate Driver and LT3999 DC-to-DC Converter to Drive a 1200 V SiC Power Module
Analog Devices Application Note
Overview The ADuM4136 gate driver features short propagation delay and fast overcurrent fault reporting via desaturation protection. These advantages, aligned with adequate external circuitry design, can satisfy the stringent requirements for exploiting the capabilities that state-of-the-art wide-band devices such as SiC and GaN semiconductors can offer.
The test results in this application note provide data from a full gate driving solution for driving a SiC MOSFET module under high voltage, with an ultra fast response, and adequate fault management via desaturation protection. This gate driving solution is powered by a low-noise, compact, power converter built with the LT3999, which provides isolated power of adequate voltage levels with low shutdown currents and soft-start capabilities.
