KEY FEATURES
The Si823x isolated driver family combines two independent, isolated drivers into a sin-
Two completely isolated drivers in one
gle package. The Si8230/1/3/4 are high-side/low-side drivers, while the Si8232/5/7/8 are
package
dual drivers. Versions with peak output currents of 0.5 A (Si8230/1/2/7) and 4.0 A
Up to 5 kV input-to-output isolation
RMS
(Si8233/4/5/8) are available. All drivers operate with a maximum supply voltage of 24 V.
Up to 1500 V peak driver-to-driver
DC
The Si823x drivers utilize Silicon Labs' proprietary silicon isolation technology, which
differential voltage
provides up to 5 kV withstand voltage per UL1577 and fast 45 ns propagation times.

HS/LS and dual driver versions
Driver outputs can be grounded to the same or separate grounds or connected to a pos-
Up to 8 MHz switching frequency
itive or negative voltage. The TTL level compatible inputs with >400 mV hysteresis are
0.5 A peak output (Si8230/1/2/7)
available in individual control input (Si8230/2/3/5/7/8) or PWM input (Si8231/4) configu-
4.0 A peak output (Si8233/4/5/8)
rations. 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 High electromagnetic immunity
gate drive applications.
