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 are dual drivers. Versions with peak output

currents of 0.5 A (Si8230/1/2) and 4.0 A (Si8233/4/5/6) 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 kV

RMS

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) 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.
