Si822x/3x Isolated Gate Drivers

Silicon Labs' Si822x/3x for a wide range of isolated MOSFET/IGBT gate drive applications

Image of Silicon Labs' Si822x/3x Isolated Gate Drivers Silicon Labs' Si8220/1 are "opto-input" package, and pin compatible single-channel isolated gate driver upgrades to HCPL-3120 and other optically-coupled gate drivers. These devices can connect to optocoupler external input circuits, for example voltage source and series limiting resistors, and offer significant improvements in performance and reliability.

The Si822x/3x isolated drivers combine two independent, isolated drivers plus an integrated isolator into a single package. The Si8230/1/3/4 are high-side/low-side drivers, and the Si8232/5/6/7/8/9 are dual drivers. Versions with peak output currents of 0.5 A (Si8230/1/2/7) and 4.0 A (Si8233/4/5/6/8/9) are available. All drivers operate with a maximum supply voltage of 24 V. The Si823x drivers utilize Silicon Labs' proprietary silicon isolation technology, which provides up to 5 kVRMS withstand voltage per UL1577 and fast 60 ns propagation times. Driver outputs can be grounded to the same or separate grounds or connected to a positive or negative voltage. The TTL level compatible inputs with >400 mV hysteresis are available in individual control input (Si8230/2/3/5/6/7/8/9) or PWM input (Si8231/4) configurations.

High integration, low propagation delay, small installed size, flexibility, and cost-effectiveness make the Si823x family ideal for a wide range of isolated MOSFET/IGBT gate drive applications.
