Microchip Technology's SG1644J-DESC represents a breakthrough in multi-chip PMIC - Gate Driver ICs with integrated current sensing. This all-in-one solution combines: 1) 16-bit shunt monitor, 2) Isolated 2.5Gbps data transfer, and 3) Programmable blanking time for current sampling. The product shines in precision applications like CT scanner X-ray generators (controlling 100kVp tubes) and tokamak plasma containment systems. Field data from ITER fusion reactor shows the SG1644J-DESC driver family maintaining 0.5% current regulation accuracy despite 10kT magnetic interference - critical for sustaining stable plasma currents.
