Microchip Technology presents the SG1644J-883B as a revolutionary PMIC - Gate Driver IC engineered for next-gen wide bandgap semiconductors. This classification excels in driving GaN HEMTs and SiC MOSFETs with <5ns delay skew between parallel channels. The product's USP includes: 1) Active Miller clamp functionality eliminating negative voltage supplies, 2) 100V/ns CMTI rating, and 3) Embedded temperature-compensated Vgs monitoring. Critical use cases involve satellite power distribution units, particle accelerator RF amplifiers, and ultra-fast EV charging piles. For illustration, NASA's Artemis lunar lander employs comparable gate drivers to manage 1.2kV SiC modules at 500kHz switching rates in vacuum environments.
