SI8261BBC-C-IP

Isolators - Gate Drivers Overview

The SI8261BBC-C-IP is a single-channel isolated gate driver from the Si826x family, designed as a digital CMOS drop-in replacement for optocoupler drivers. It utilizes capacitive coupling technology to provide 3750Vrms isolation and features a peak output current of 4A. The device operates with a supply voltage range of 6.5V to 30V and includes a 12V under-voltage lockout (UVLO). Key electrical parameters include a typical rise time of 5.5ns and fall time of 8.5ns, with maximum propagation delays of 60ns (tpLH) and 50ns (tpHL). It offers a minimum common-mode transient immunity of 35kV/µs and functions within a temperature range of -40°C to +125°C.

Isolators - Gate Drivers Feature Summary

• Provides superior common-mode transient immunity and robust performance compared to traditional optocoupler drivers.
• Features a digital CMOS interface that serves as a direct pin-compatible replacement for legacy opto-drivers.
• Incorporates integrated UVLO protection to ensure reliable switching under varying supply conditions.

Isolators - Gate Drivers Applications

• Solar power inverters
• Switched-mode power supplies (SMPS)
• Uninterruptible power supplies (UPS)

Isolators - Gate Drivers Procurement Notes

Verify component status carefully, as specific variants within the Si826x series may be subject to end-of-life notifications or discontinuation. Confirm package type accuracy, distinguishing between surface-mount and through-hole DIP options. Ensure compatibility with existing PCB footprints when replacing legacy optocouplers. Validate isolation ratings against application safety requirements. Check for updated datasheets regarding recent manufacturing changes or certification updates.

Isolators - Gate Drivers Selection Notes

Select this component for applications requiring high reliability and long-term fail-safe operation, such as those needing up to 20 years of warranty support. Choose based on the need for superior noise immunity in high-power environments. Consider the package form factor for board space constraints. Evaluate the trade-off between speed and isolation voltage if higher CMTI is required. Ensure the driving logic levels match the CMOS input requirements.
