Product Information

Back to top
The Si823x isolated driver family combines two independent, isolated drivers into a single package. 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 45 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 or PWM input  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.

• Power delivery systems
• Motor control systems
• Isolated dc-dc power supplies
• Lighting control systems
• Plasma displays
• Solar and industrial inverters
