Si827x Data Sheet 4 Amp ISOdriver with High Transient (dV/dt) Immunity The Si 827x isolators are ideal for driving po wer switches used in a wide variety of power supply, inverter, and motor contr ol applications. The Si827x isolated ga te drivers utilize Silicon Laboratories ' proprietary silicon isolation technol ogy, supporting up to 2.5 kVRMS withsta nd voltage per UL1577 and VDE0884. This technology enables industry leading co mmon-mode transient immunity (CMTI), ti ght timing specifications, reduced vari ation with temperature and age, better part-to-part matching, and extremely hi gh reliability. It also offers unique f eatures such as separate

pull-up/down outputs, driver shutdown on UVLO fault, and precise dead time prog rammability. The Si827x series offers l onger service life and dramatically hig her reliability compared to opto-couple d gate drivers. The Si827x drivers uti lize Silicon Labs' proprietary silicon isolation technology, which provides up to 2.5 kVRMS withstand voltage per UL1 577 and fast 60 ns propagation times. D river outputs can be grounded to the sa me or separate grounds or connected to a positive or negative voltage. The TTL level compatible inputs with >400 mV h ysteresis are available in individual c ontrol input (Si8271/2/3/5) or PWM inpu t (Si8274) configurations. High integra tion, low propagation delay, small inst alled size, flexibility, and costeffect iveness make the Si827x family ideal fo r a wide range of isolated MOSFET/IGBT and SiC or GaN FET gate drive applicati ons. Automotive Grade is available for certain part numbers. These products a re built using automotive-specific flow s at all steps in the manufacturing pro cess to ensure the robustness and low d efectivity required for automotive appl ications.
