SI8230BB-D-ISR

Isolators - Gate Drivers Overview

The SI8230BB-D-ISR is a dual-channel galvanically isolated gate driver from the Si823x series, manufactured by Skyworks Solutions Inc. It features a 2.5 kVrms isolation voltage and an 8 V under-voltage lockout (UVLO). The device operates within a temperature range of -40°C to +125°C and dissipates up to 1.2 W. Key electrical parameters include a maximum propagation delay of 45 ns, with rise and fall times of 20 ns each. It provides 500 mA output current and draws 3.5 mA in quiescent operation. The component is housed in a 16-pin SOIC-Wide package and is supplied in tape-and-reel format.

Isolators - Gate Drivers Feature Summary

• Provides high electromagnetic immunity for reliable operation in noisy industrial environments
• Integrates high-side and low-side drive capabilities within a single compact package
• Utilizes capacitive coupling technology for galvanic isolation between input and output circuits

Isolators - Gate Drivers Applications

• Industrial motor control systems requiring robust isolation
• Automotive power electronics applications meeting AEC-Q100 standards
• Inverter and converter topologies needing high-side switching

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix D-ISR confirms the tape-and-reel packaging configuration rather than tube packaging. Ensure the BB designation aligns with the required 2.5 kVrms isolation rating and 8 V UVLO threshold for your circuit design. Confirm compatibility with standard SOIC-Wide-16 footprints during PCB layout validation.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated driver with 2.5 kVrms isolation is required alongside automotive qualification. The 500 mA peak output current supports driving medium-power MOSFETs or IGBTs efficiently. Consider the 45 ns propagation delay for timing-sensitive applications where moderate speed is sufficient compared to faster alternatives.

Isolators - Gate Drivers Part Context

This part belongs to the Si823x family of isolated gate drivers, which are designed for high-performance power conversion. The family includes variants with different isolation voltages and UVLO settings. The SI8230BB variant specifically targets applications needing 2.5 kVrms isolation with automotive reliability certification.

Isolators - Gate Drivers Replacement Considerations

SI8230BC-D-ISR offers similar functionality but with increased 3.75 kVrms isolation voltage. SI8230BD-D-ISR provides 5 kVrms isolation capability. Verify pinout compatibility and thermal performance before substituting these higher-isolation variants.
