Si823x Data Sheet

0.5 and 4.0 Amp ISOdrivers (2.5 and 5 kV

RMS

)

The Si823x isolated driver family combines two independent, isolated drivers into a sin-

gle package. The Si8230/1/3/4 are high-side/low-side drivers, while the Si8232/5/7/8 are

dual drivers. Versions with peak output currents of 0.5 A (Si8230/1/2/7) and 4.0 A

(Si8233/4/5/8) 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 kV

RMS

withstand voltage per UL1577 and fast 45 ns propagation times.

Driver outputs can be grounded to the same or separate grounds or connected to a pos-

itive or negative voltage. The TTL level compatible inputs with >400 mV hysteresis are

available in individual control input (Si8230/2/3/5/7/8) or PWM input (Si8231/4) configu-

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

gate drive applications.

Automotive Grade is available for certain part numbers. These products are built using

automotive-specific flows at all steps in the manufacturing process to ensure the robust-

ness and low defectivity required for automotive applications.
