SI823H5CB-AS1R

Isolators - Gate Drivers Overview

The SI823H5CB-AS1R is a dual-channel isolated gate driver from the Si823Hx series, manufactured by Skyworks Solutions. It features capacitive coupling technology for galvanic isolation with a rating of 2500 Vrms. The device operates within a supply voltage range of 3 V to 5.5 V and supports an operating temperature range from -40°C to +125°C. Packaged in a narrow-body SOIC-16 format, it provides two independent drivers for high-side and low-side switching applications.

Isolators - Gate Drivers Feature Summary

• Utilizes silicon dioxide (SiO2) capacitive isolation technology for robust signal transmission across isolation barriers.
• Provides dual-channel configuration suitable for half-bridge and full-bridge power converter topologies.
• Offers high common-mode transient immunity to ensure reliable operation in electrically noisy environments.

Isolators - Gate Drivers Applications

• Industrial motor drives and inverters
• Automotive power electronics systems
• Solar micro-inverters and DC-AC conversion

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix AS1R indicates reel packaging when sourcing components. Confirm that the 2500 Vrms isolation rating meets the safety requirements of the target application. Ensure compatibility with the narrow-body SOIC-16 footprint during PCB layout verification. Check for AEC-Q100 qualification if automotive reliability standards are mandatory for the design.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated driver with 2500 Vrms isolation is required in a compact surface-mount package. It is appropriate for designs needing high common-mode transient immunity and wide operating temperature ranges. Consider alternative variants within the Si823Hx family if higher isolation ratings or different pin configurations are necessary for the specific system architecture.
