SI8233BB-D-IM1R

Isolators - Gate Drivers Overview

The SI8233BB-D-IM1R is a dual-channel isolated gate driver from the Si823x series, manufactured by Skyworks Solutions Inc. It utilizes silicon isolation technology to provide 2500Vrms input-to-output isolation voltage. The device features a high-side and low-side configuration with an 8V UVLO threshold. It operates within a supply voltage range of 9.4V to 24V and delivers peak output currents of 2A for the high-side and 4A for the low-side channels. Propagation delays are specified at a maximum of 60ns, with rise and fall times of 12ns. The component is housed in a 14-QFN (5x5mm) package and supports AEC-Q100 automotive qualification.

Isolators - Gate Drivers Feature Summary

• Integrated overlap protection and programmable dead-time control
• TTL-compatible inputs with hysteresis

Isolators - Gate Drivers Applications

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

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IM1R' against official Skyworks documentation to confirm the 14-QFN package and reel packaging format. Ensure the 2500Vrms isolation rating matches system requirements, as other variants in the family offer higher ratings. Confirm AEC-Q100 compliance if automotive application is intended. Cross-reference datasheet revision dates to ensure compatibility with current manufacturing processes.

Isolators - Gate Drivers Selection Notes

Select this part when a compact 14-pin QFN footprint is required for dual-channel isolation. The 8V UVLO setting suits applications where lower turn-on thresholds are beneficial. Compare propagation delay specifications against switching frequency requirements. Verify that the 2500Vrms isolation level meets safety standards for the target circuit, noting that higher isolation variants exist within the same product family.

Isolators - Gate Drivers Part Context

This component belongs to the Si823x family of isolated gate drivers, which also includes variants like SI8233BD-D-ISR offering 5kV isolation in different packages. The manufacturer transitioned from Silicon Laboratories to Skyworks Solutions. The IM1R suffix denotes the specific tape-and-reel packaging for the QFN form factor, distinguishing it from tube-packaged or SOIC versions.

Isolators - Gate Drivers Replacement Considerations

SI8233BB-D-IM1 is the non-reel equivalent. SI8233BD-D-ISR offers 5kV isolation in a 16-SOIC package.
