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.

Industrial and Automotive Grade OPNs
Industrial-grade devices (part numbers having an “-I” in their suffix) are built using well-controlled, high-quality manufacturing flows to
ensure robustness and reliability. Qualifications are compliant with JEDEC, and defect reduction methodologies are used throughout
definition, design, evaluation, qualification, and mass production steps.
Automotive-grade devices (part numbers having an “-A” in their suffix) are built using automotive-specific flows at all steps in the manu-
facturing process to ensure robustness and low defectivity. These devices are supported with AIAG-compliant Production Part Approval
Process (PPAP) documentation, and feature International Material Data System (IMDS) and China Automotive Material Data System
(CAMDS) listing. Qualifications are compliant with AEC-Q100, and a zero-defect methodology is maintained throughout definition, de-
sign, evaluation, qualification, and mass production steps.
