The SI8244BB-D-IS1R is a digital isolator and isolated gate driver
featuring high-side, bidirectional isolation with integrated drivers and
power supply components. Built using Silicon Labs' proprietary isolation
technology, it provides 5.5 kVrms isolation, supports up to 150 Mbps data transmission, and delivers exceptional 50 kV/μs CMTI immunity for
operation in noisy high-voltage environments.
The device includes built-in safety features such as input/output clamps, short-circuit detection, thermal shutdown and undervoltage lockout. This enhances reliability while reducing external component requirements. With operation from -40°C to +125°C and a compact 16-SOIC package, the SI8244BB-D-IS1R is well-suited for motor drives, solar inverters, power converters and industrial automation where isolation, speed and safety are essential.
Provides up to 5.5 kVrms isolation with 50 kV/μs CMTI, ensuring reliable operation in harsh industrial and automotive environments.
Supports data rates up to 150 Mbps, suitable for high-performance control systems requiring fast and accurate gate-driving signals.
Incorporates built-in drivers, power supply support, clamp circuits, short-circuit detection and thermal shutdown to simplify system design and enhance safety.
Designed for robust field operation from -40°C to +125°C, making it suitable for industrial motors, power inverters and factory automation.
Provides fully isolated control for multiple power switches with high-side or bidirectional signaling support.
Includes UVLO, thermal shutdown, output clamp circuits and fault reporting, ensuring safe operation in complex power systems.
5.5 kVrms isolation voltage combined with 150 Mbps data rate enables fast and secure communication across isolated power domains.
