Si827x Data Sheet
4 Amp ISOdriver with High Transient (dV/dt) Immunity
KEY FEATURES
The Si827x isolators are ideal for driving power switches used in a wide variety of power
supply, inverter, and motor control applications. The Si827x isolated gate drivers utilize
Silicon Laboratories' proprietary silicon isolation technology, supporting up to 2.5 kV
RMS
withstand voltage per UL1577 and VDE0884. This technology enables industry leading
common-mode transient immunity (CMTI), tight timing specifications, reduced variation
with temperature and age, better part-to-part matching, and extremely high reliability. It
also offers unique features such as separate pull-up/down outputs, driver shutdown on
UVLO fault, and precise dead-time programmability. The Si827x series offers longer
service life and dramatically higher reliability compared to opto-coupled gate drivers.
The Si827x drivers utilize Silicon Labs' proprietary silicon isolation technology, which
provides up to 2.5 kV
RMS
withstand voltage per UL1577 and fast 60 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 (Si8271/2/3/5) or PWM input (Si8274) configura-
tions. High integration, low propagation delay, small installed size, flexibility, and cost-
effectiveness make the Si827x family ideal for a wide range of isolated MOSFET/IGBT
and SiC or GaN FET gate drive applications.
Automotive Grade products are built using automotive-specific flows at all steps in the
manufacturing process to ensure the robustness and low defectivity required for auto-
motive 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 employed throughout definition, de-
sign, evaluation, qualification, and mass production steps.

Note:
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 Ordering Part Number indicates tape and reel option.
4. Automotive-Grade devices (with an “-A” suffix) are identical in construction materials and electrical parameters to their Industrial-
Grade (with an “-I” suffix) version counterpart. 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. In Top Markings, the Manufacturing Code represented by “TTTTTT” contains, as its first character, a letter in the range N through
Z to indicate Automotive-Grade.
6. All HS/LS drivers have built-in overlap protection while the single and dual drivers do not.
