SI8230BB-D-IS1

Isolators - Gate Drivers Overview

The SI8230BB-D-IS1 is a galvanically isolated gate driver from Skyworks Solutions, featuring two independent channels for high-side and low-side switching. It provides up to 5 kVRMS input-to-output isolation and supports peak driver-to-driver isolation of 1500 VDC. The device operates with an output current capability of 500 mA and includes an 8 V under-voltage lockout (UVLO). It functions within a supply voltage range of 4.5 V to 6.5 V and is housed in a 16-pin SOIC package.

Isolators - Gate Drivers Feature Summary

• Provides complete galvanic isolation between input control signals and power stage outputs
• Integrates dual independent drivers for simultaneous high-side and low-side MOSFET or IGBT control
• Includes built-in under-voltage lockout to prevent improper switching during low supply conditions

Isolators - Gate Drivers Applications

• Isolated motor drive systems requiring robust signal separation
• Inverter circuits in renewable energy conversion equipment
• Industrial power supplies utilizing high-frequency switching topologies

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'D' against the manufacturer's latest datasheet to confirm pinout configuration and isolation ratings. Ensure the selected package variant matches the PCB footprint requirements. Cross-reference the AEC-Q100 qualification status if automotive reliability standards are mandatory for the target application environment.

Isolators - Gate Drivers Selection Notes

Select this component when high common-mode transient immunity and significant isolation voltage are required between control logic and power devices. Consider the 500 mA peak output current for driving medium-power MOSFETs or IGBTs. Evaluate the 16-pin SOIC form factor for space-constrained designs needing dual-channel isolation without external transformers.

Isolators - Gate Drivers Part Context

This part belongs to the Si823x family of isolated gate drivers designed for demanding power electronics applications. The series utilizes capacitive coupling technology to achieve high isolation performance while maintaining fast signal transmission. It serves as a critical interface component bridging low-voltage controllers with high-voltage power switches.

Isolators - Gate Drivers Replacement Considerations

Check for direct substitutes within the Si823x series, such as the SI8230BB-IS1, ensuring isolation ratings and pin compatibility match. Verify that alternative components support the required 500 mA output current and 5 kVRMS isolation level.
