SI823H2CD-IS3R

Isolators - Gate Drivers Overview

The SI823H2CD-IS3R is a dual-channel isolated gate driver from the Skyworks Si823Hx series, designed for high-voltage power switching applications. It features a 5 kV RMS isolation rating and utilizes silicon technology for reliable signal transmission across isolation barriers. The device is housed in a wide SOIC-14 surface-mount package, suitable for automated assembly. It operates within an extended temperature range of -40°C to +125°C and holds AEC-Q100 qualification for automotive reliability standards. The component includes undervoltage lockout (UVLO) functionality to ensure safe operation under varying supply conditions.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation between control circuitry and power switches with a 5 kV rating.
• Delivers independent drive signals for high-side and low-side power devices.
• Incorporates UVLO mechanisms to prevent partial turn-on or shoot-through conditions.
• Utilizes silicon-based capacitive coupling for robust signal integrity.

Isolators - Gate Drivers Applications

• Automotive electric vehicle motor drives
• Industrial inverter systems
• High-frequency power supply topologies

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS3R indicates reel packaging when ordering. Confirm that the AEC-Q100 qualification meets project requirements for automotive-grade components. Ensure the SOIC-14 footprint matches the PCB layout design. Check datasheet specifications for operating voltage ranges and thermal dissipation limits before integration.

Isolators - Gate Drivers Selection Notes

Select this model for applications requiring high isolation voltage and dual-channel output in a compact surface-mount form factor. Consider the propagation delay characteristics for high-speed switching requirements. Evaluate the thermal performance within the intended enclosure environment. Compare against single-channel alternatives if only one output is required.

Isolators - Gate Drivers Part Context

This component belongs to the Si823Hx family of isolated gate drivers manufactured by Skyworks Solutions. The family offers various channel configurations and isolation ratings tailored for power electronics. The SI823H2CD variant specifically addresses dual-driver needs with enhanced isolation capabilities compared to lower-rated series members.

Isolators - Gate Drivers Replacement Considerations

Consult official Skyworks documentation for cross-reference data. Verify pin compatibility and electrical parameters before substituting with other dual-channel isolated gate drivers. Ensure any alternative part meets the same 5 kV isolation and AEC-Q100 requirements.
