The Si8281CD-IS is an isolated gate driver with an integrated DC-DC converter, designed for driving SiC FETs, power MOSFETs, and IGBTs in motor control and inverter applications. It features a 20-pin wide-body SOIC package, 3.75 kVrms isolation per UL1577, and a 12 V UVLO threshold. The device includes DESAT detection, soft shutdown, an integrated Miller clamp, and a power-ready output. It supports complementary digital inputs, operates with a 3.0 to 5.5 V supply voltage, and delivers 83% DC-DC converter efficiency. The part is industrially rated with a temperature range of -40 to 125 °C and complies with RoHS standards and JEDEC manufacturing qualifications. It does not include external switch control, shutdown, soft start, or programmable frequency features, as these are exclusive to the Si8283 and Si8284 variants.
