SI823H5AB-IM1R

Isolators - Gate Drivers Overview

The SI823H5AB-IM1R is a dual-channel isolated gate driver from the Si823Hx series, manufactured by Skyworks Solutions Inc. It features a DFN-14 package with surface-mount installation. The device provides 2.5 kVrms insulation voltage and operates within a temperature range of -40°C to +125°C. Key electrical parameters include a maximum propagation delay of 30 ns, rise time of 12 ns, and fall time of 12 ns. It supports an input voltage range of 3 V to 5.5 V and delivers a maximum continuous output current of 4 A. The driver has a working supply current of 2.2 mA and outputs up to 30 V. It is moisture sensitive and comes in a reel packaging format.

Isolators - Gate Drivers Feature Summary

• Provides high-speed signal isolation with low propagation delay for precise timing control
• Features robust capacitive coupling technology ensuring reliable operation across wide temperature ranges
• Delivers strong drive capability suitable for powering power switches efficiently

Isolators - Gate Drivers Applications

• Industrial motor drives requiring galvanic isolation
• Inverter circuits in renewable energy systems
• High-voltage switching applications in power supplies

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IM1R indicates reel packaging versus other variants like IM1 or IM. Confirm the 2.5 kVrms isolation rating matches system requirements rather than higher voltage options. Check for AEC-Q100 qualification if automotive use is intended, as this variant may differ from qualified counterparts. Ensure compatibility with 3 V to 5.5 V logic levels on both sides.

Isolators - Gate Drivers Selection Notes

Select this part when dual-channel isolation is required with moderate speed needs under 30 ns. Compare against SI823H5BB-IM1 for QFN-14 alternatives or SI823H5CD-IS3 for 5 kV isolation. Consider the DFN-14 footprint constraints and thermal performance. Verify that the 4 A output current suffices for the target gate charge requirements without needing parallel drivers.

Isolators - Gate Drivers Part Context

This component belongs to the Si823Hx family of isolated gate drivers, which utilize silicon dioxide (SiO2) dielectric technology for high-reliability isolation. The family includes various packages and isolation ratings. This specific model focuses on industrial applications where 2.5 kV isolation is sufficient, offering a balance between performance and cost compared to higher-rated automotive versions.

Isolators - Gate Drivers Replacement Considerations

SI823H5AB-IM1 is a tray-packaged equivalent with identical electrical characteristics. SI823H5CB-IMR offers similar specs but in a different package configuration. Direct substitutes must maintain the 2.5 kVrms rating and DFN-14 form factor to ensure board compatibility.
