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 voltage per UL1577 and
RMS
10kV surge protection per VDE 0884-10. 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.
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
robustness and low defectivity required for automotive applications.
