Description
The Si826x isolators are pin-compatible, drop-in upgrades for popular opto-
coupled gate drivers, such as 0.6 A ACPL-0302/3020, 2.5 A HCPL-3120/ACPL-
3130, HCNW3120/3130, and similar opto-drivers. The devices are ideal for driving
power MOSFETs and IGBTs used in a wide variety of inverter and motor control
applications. The Si826x isolated gate drivers utilize Silicon Laboratories'
proprietary silicon isolation technology, supporting up to 5.0 kV withstand
RMS
voltage per UL1577 and 10kV surge protection per IEC60747. This technology
enables higher-performance, reduced variation with temperature and age, tighter
part-to-part matching, and superior common-mode rejection compared to opto-
coupled gate drivers. While the input circuit mimics the characteristics of an LED,
less drive current is required, resulting in higher efficiency. Propagation delay time
is independent of input drive current, resulting in consistently short propagation
times, tighter unit-to-unit variation, and greater input circuit design flexibility. As a
result, the Si826x series offers longer service life and dramatically higher reliability
compared to opto-coupled gate drivers.
