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
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.
