Silicon Labs Si823x Isolated Drivers

Silicon Labs' Si823x Isolated Drivers combines two independent, isolated drivers 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 0.5A (Si8230/1/2/7) and 4.0A (Si8233/4/5/6/8/9) are available. All drivers operate with a maximum supply voltage of 24V. The Si823x drivers utilize Silicon Labs' proprietary silicon isolation technology, which provides up to 5kVRMS withstand voltage per UL1577 and fast 60ns 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 >400mV 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.
