1 / 57 page Rev. 1.7 4/15 Copyright © 2015 by Silicon Laboratories Si823x Si823x 0.5 AND 4.0 A MP ISO DRIVERS (2.5 AND 5 KV RMS) Features Applications Safety Approval Description The Si823x isolated driver family 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 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) 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) 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.
