SI823H2BD-IS3R

Isolators - Gate Drivers Overview

The SI823H2BD-IS3R is a current-isolated gate driver from the Si823Hx series, manufactured by Skyworks Solutions Inc. It features a wide-body SOIC-14 package and supports high-side and low-side configurations with non-inverting logic. The device operates within a supply voltage range of 3 V to 5.5 V and delivers an output current of 5.9 mA. Key electrical parameters include a maximum propagation delay of 30 ns, rise and fall times of 12 ns each, and a peak output voltage of 30 V. It is qualified under AEC-Q100 standards for automotive applications and functions reliably across a temperature range of -40°C to +125°C.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation using silicon technology for robust signal transmission between control and power stages.
• Supports dual-channel operation suitable for half-bridge and high-side/low-side driver topologies.
• Features non-inverting logic configuration compatible with TTL logic inputs.

Isolators - Gate Drivers Applications

• Automotive motor control systems requiring isolated gate driving.
• Industrial inverter and converter circuits utilizing half-bridge configurations.
• Power management units needing reliable high-side and low-side switching signals.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS3R confirms the reel packaging format against your assembly requirements. Confirm that the AEC-Q100 qualification aligns with your automotive grade specifications. Ensure the wide-body SOIC-14 footprint matches your PCB layout constraints. Check for any recent product change notices regarding manufacturing location or material composition updates.

Isolators - Gate Drivers Selection Notes

Select this component when a current-isolated driver with moderate output drive capability is required. The 5.9 mA output current suits smaller MOSFETs or IGBTs where high peak current is not critical. The wide-body package facilitates higher creepage distances compared to standard packages. Consider the 30 ns propagation delay for timing-sensitive applications within the specified operating temperature range.

Isolators - Gate Drivers Part Context

This part belongs to the Si823Hx family of isolated gate drivers designed for demanding industrial and automotive environments. The series utilizes Skyworks' proprietary silicon isolation technology to replace traditional magnetic transformers. The H2 variant specifically denotes the channel count and configuration within the broader portfolio of similar isolation devices.

Isolators - Gate Drivers Replacement Considerations

Check for SI823H2BD-IS3 as a tube-packaged alternative if reel quantities are not required. Verify compatibility with SI823H1BD-AS3 or SI823H8BD-IS3R for pin-compatible options within the same series, ensuring electrical parameters meet design needs.
