SI823H4CD-IS3R

Isolators - Gate Drivers Overview

The SI823H4CD-IS3R is a single-channel isolated gate driver from Skyworks Solutions, designed for high-speed power switching applications. It features capacitive coupling technology providing 5000Vrms isolation voltage within a 14-WB SOIC package. The device supports a supply voltage range of 3V to 5.5V and delivers a peak output current of 6A. It operates reliably across an extended temperature range from -40°C to +125°C and holds AEC-Q100 qualification for automotive reliability standards.

Isolators - Gate Drivers Feature Summary

• Capacitive coupling technology ensures robust signal transmission with high common-mode transient immunity.
• Single-channel configuration simplifies half-bridge or high-side switch driving requirements.
• Integrated undervoltage lockout (UVLO) protects against improper operation during power-up and shutdown sequences.

Isolators - Gate Drivers Applications

• Automotive motor control systems
• Industrial inverter drives
• High-frequency DC-DC converters

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS3R indicates reel packaging when placing orders. Confirm that the 14-WB SOIC footprint matches your PCB layout constraints. Ensure compatibility with the required logic input levels and check for any recent design changes in the official datasheet before finalizing procurement specifications.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel driver with 6A peak current capability is required. The wide operating temperature range makes it suitable for harsh environments. Consider the 5kV isolation rating for safety-critical applications requiring galvanic separation between control and power stages.

Isolators - Gate Drivers Part Context

This part belongs to the Si823Hx series of isolated gate drivers. The series utilizes Skyworks' proprietary capacitive isolation technology. Other members in this family offer varying channel counts and current ratings while maintaining similar form factors and isolation characteristics for modular design approaches.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include other single-channel variants within the Si823Hx series such as the SI823H9BD-IS4, though pinouts and current ratings may differ. Always verify electrical parameters and package dimensions against the original specification before substitution.
