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
single 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 Skyworks' proprietary silicon isolation technology, which pro-
vides 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
positive 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)
configurations. High integration, low propagation delay, small installed size, flexibility,
and cost-effectiveness make the Si823x family ideal for a wide range of isolated MOS-
FET/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.

1. Ordering Guide
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
manufacturing 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, design, evaluation, qualification, and mass production steps.

1. All packages are RoHS-compliant with peak reflow temperatures of 260 °C according to the JEDEC industry standard classifica-
tions and peak solder temperatures.
2. “Si” and “SI” are used interchangeably.
3. An "R" at the end of the part number denotes tape and reel packaging option.
4. The temperature ranges is –40 to +125 °C.
5. Automotive-Grade devices (with an "–A" suffix) are identical in construction materials, topside marking, and electrical parameters
to their Industrial-Grade (with an "–I" suffix) version counterparts. Automotive-Grade products are produced utilizing full automo-
tive process flows and additional statistical process controls throughout the manufacturing flow. The Automotive-Grade part
number is included on shipping labels.
6. In the top markings of each device, the Manufacturing Code represented by either “RTTTTT” or “TTTTTT” contains as its first
character a letter in the range N through Z to indicate Automotive-Grade.
