Si827x Data Sheet
4 Amp ISOdriver with High Transient (dV/dt) Immunity
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
kVRMS 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 reli-
ability. It also offers unique features such as separate pull-up/down outputs, driver shut-
down on UVLO fault, and precise dead time programmability. The Si827x series offers
longer service life and dramatically higher reliability compared to opto-coupled gate driv-
ers.
The Si827x drivers utilize Silicon Labs' proprietary silicon isolation technology, which
provides up to 2.5 kVRMS 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 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.
