Si8239x Data Sheet
4.0 A ISODrivers with 2.5 V VDDI and Safety Features
KEY FEATURES
The Si8239x combines two isolated drivers with either an independent input control or a
single input into a single package for high power applications. All drivers operate with a
2.5 V input VDD and a maximum drive supply voltage of 24 V.
The Si8239x isolators are ideal for driving power MOSFETs and IGBTs used in a wide
variety of switched power and motor control applications. These drivers utilize Silicon
Laboratories' proprietary silicon isolation technology, supporting up to 5 kVRMS with-
stand voltage. This technology enables high CMTI (100 kV/µs), lower prop delays and
skew, reduced variation with temperature and age and tighter part-to-part matching.
It also offers some unique features such as an output UVLO fault detection and feed-
back, and automatic shutdown for both drivers, an EN (active high) pin, a safe delayed
start-up time of 1 ms, fail-safe drivers with default low in case of VDDI power-down, and
dead time programmability. The Si8239x family offers longer service life and dramatical-
ly higher reliability compared to opto-coupled gate drivers.
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) listings. Qualifications are com-
pliant with AEC-Q100, and a zero-defect methodology is maintained throughout definition, design, evaluation, qualification, and mass
production steps.

3. “Si” and “SI” are used interchangeably.
4. An "R" at the end of the part number denotes tape and reel packaging option.
5. 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.
6. Referring to Section 11 “Top Markings”, 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.
7. Additional Ordering Part Numbers may be available in Automotive-Grade. Please contact your local Silicon Labs sales represen-
tative for further information.
