Si823x Data Sheet0.5 and 4.0 Amp ISOdrivers (2.5 and 5 kVRMS)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 aredual 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, whichprovides 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 pos-itive or negative voltage. The TTL level compatible inputs with >400 mV hysteresis areavailable 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/IGBTgate drive applications.Automotive Grade is available for certain part numbers. These products are built usingautomotive-specific flows at all steps in the manufacturing process to ensure the robust-ness and low defectivity required for automotive applications.KEY FEATURES• Two completely isolated drivers in onepackage• Up to 5 kVRMS input-to-output isolation• Up to 1500 VDC peak driver-to-driverdifferential voltage• HS/LS and dual driver versions• Up to 8 MHz switching frequency• 0.5 A peak output (Si8230/1/2/7)• 4.0 A peak output (Si8233/4/5/8)• High electromagnetic immunity• RoHS-compliant packages:• SOIC-14/16 wide body• SOIC-16 narrow body• LGA-14• QFN-14 (pin to pin compatible withLGA-14 packages)• AEC-Q100 qualification• Automotive-grade OPNs available• AIAG compliant PPAP documentationsupport• IMDS and CAMDS listing supportIndustrial Applications• Power delivery systems• Motor control systems• Isolated dc-dc power supplies• Lighting control systems• Plasma displays• Solar and industrial invertersSafety Regulatory Approvals• UL 1577 recognized• Up to 5000 VRMS for 1 minute• CSA component notice 5A approval• IEC 60950-1, 62368-1, 60601-1 (re-inforced insulation)• VDE certification conformity• VDE 0884-10• EN60950-1 (reinforced insulation)• CQC certification approval• GB4943.1Automotive Applications• On-board chargers• Battery management systems• Charging stations• Traction inverters• Hybrid Electric Vehicles• Battery Electric Vehiclessilabs.com | Building a more connected world.Rev. 2.14
