SI8234BB-C-IS

Isolators - Gate Drivers Overview

The SI8234BB-C-IS is a dual-channel, galvanically isolated gate driver from the Si823x series by Skyworks Solutions. It features capacitive coupling technology with 2500 Vrms isolation voltage and supports high-side and low-side configurations in a 16-SOIC package. The device delivers a peak output current of 4 A with propagation delays up to 60 ns and rise/fall times of 12 ns. It operates within a temperature range of -40°C to +125°C and includes an 8 V undervoltage lockout (UVLO). This component is designed for industrial applications requiring high electromagnetic immunity.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'C' indicates the correct insulation rating and package variant for your design requirements. Confirm availability status as manufacturing changes may occur. Ensure the 2500 Vrms isolation specification meets your safety standards. Check for moisture sensitivity level handling during assembly. Validate that the SOIC-16 footprint matches your PCB layout constraints.

Isolators - Gate Drivers Selection Notes

Select this part when 2500 Vrms isolation is sufficient compared to higher-rated variants like the SI8234BD series. Consider the 4 A peak current capability for driving medium-power MOSFETs or IGBTs. Evaluate the 60 ns propagation delay against timing requirements. Compare the SOIC-16 narrow package against wide package options if thermal dissipation is a concern. Verify AEC-Q100 qualification if automotive reliability is not required but industrial ruggedness is.
