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.

Automotive Grade OPNs
Automotive-grade devices are built using automotive-specific flows at all steps in the manufacturing process to ensure robustness and
low defectivity. These devices are supported with AIAG-compliant Production Part Approval Process (PPAP) documentation, and fea-
ture International Material Data System (IMDS) and China Automotive Material Data System (CAMDS) listing. Qualifications are compli-
ant with AEC-Q100, and a zero-defect methodology is maintained throughout definition, design, evaluation, qualification, and mass pro-
duction steps.

1. All packages are RoHS-compliant with peak reflow temperatures of 260 °C according to the JEDEC industry standard classifica-
tions.
2. “Si” and “SI” are used interchangeably.
3. An "R" at the end of the part number denotes tape and reel packaging option.
4. Automotive-Grade devices (with an "–A" suffix) are identical in construction materials, topside marking, and electrical parameters
to their Industrial-Grade (with a "–I" suffix) version counterparts. Automotive-Grade products are produced utilizing full automotive
process flows and additional statistical process controls throughout the manufacturing flow. The Automotive-Grade part number is
included on shipping labels.
5. Additional Ordering Part Numbers may be available in Automotive-Grade. Please contact your local Silicon Labs sales represen-
tative for further information.
