SI8230BD-D-IS3R

Isolators - Gate Drivers Overview

The SI8230BD-D-IS3R is a dual-channel galvanically isolated gate driver from the Si823x series, manufactured by Skyworks Solutions. It utilizes silicon isolation technology to provide 5 kVrms insulation voltage with an 8 mm creepage distance. The device features high-side and low-side configurations with TTL logic inputs. Key electrical parameters include a maximum propagation delay of 45 ns, rise and fall times of 20 ns, and a peak output current of 500 mA. It operates within a supply voltage range of 4.5 V to 5.5 V for the input side and supports up to 24 V on the output side. The component is AEC-Q100 qualified and housed in a 14-pin SOIC-Wide package.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation via silicon-based capacitive coupling technology.
• Features high electromagnetic immunity (EMI) suitable for industrial environments.
• Includes undervoltage lockout (UVLO) with an 8 V threshold for reliable operation.
• Supports independent ground references for high-side and low-side outputs.

Isolators - Gate Drivers Applications

• Motor drive and control systems
• Industrial power management circuits
• Isolated MOSFET and IGBT gate driving

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS3R corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 8 mm creepage specification meets the safety clearance requirements of your target application's regulatory standards. Ensure compatibility with the 14-pin SOIC-Wide footprint during PCB layout verification.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel driver with 5 kVrms isolation and moderate switching speeds is required. The 500 mA output current is suitable for smaller MOSFETs or IGBTs. Consider the 45 ns propagation delay for applications where precise timing synchronization between channels is critical but ultra-high speed is not mandatory compared to faster alternatives.

Isolators - Gate Drivers Part Context

This part belongs to the Si823x family of isolated gate drivers, which are designed for high-voltage isolation applications. The family offers various channel counts and output currents, utilizing Skyworks' proprietary silicon isolation technology to replace traditional optocouplers with higher reliability and better performance characteristics in power electronics designs.

Isolators - Gate Drivers Replacement Considerations

Check for direct substitutes within the Si823x series such as SI8230AD-D-IS3R, noting differences in UVLO thresholds. Verify pinout compatibility with other 14-pin SOIC wide isolated drivers if cross-referencing with competitors' offerings.
