SI8273GBD-IS1

Isolators - Gate Drivers Overview

The SI8273GBD-IS1 is a high-speed, galvanically isolated gate driver from Skyworks Solutions. It features a single channel with high-side and low-side outputs in a 16-SOIC package. Key electrical parameters include an isolation voltage of 2.5 kVrms, maximum propagation delay of 75 ns, rise time of 16 ns, and fall time of 18 ns. The device supports input voltages between 2.5 V and 5.5 V, operates on a supply current of 10 mA, and delivers 4 mA output current at 12 V. It is AEC-Q100 qualified for automotive use, with an operating temperature range of -40°C to +125°C and power dissipation of 1.2 W.

Isolators - Gate Drivers Feature Summary

• High common-mode transient immunity (CMTI) for reliable operation in noisy environments
• Integrated under-voltage lockout (UVLO) for both high-side and low-side drivers
• Deglitching circuitry to prevent false triggering during switching events

Isolators - Gate Drivers Applications

• Automotive motor control systems
• Industrial inverter drives
• Solid-state transformer applications

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1R or IS1 against the datasheet to confirm packaging type, as these indicate reel or tube configurations respectively. Ensure the order matches the required AEC-Q100 qualification status if used in automotive contexts. Confirm the SOIC-16 package dimensions align with PCB layout requirements before finalizing procurement orders.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed isolation with precise timing is required. The 75 ns max delay and low skew make it suitable for synchronous rectification. Compare against non-automotive grades if cost is a primary constraint, but retain this part for applications demanding AEC-Q100 reliability and extended temperature performance.

Isolators - Gate Drivers Part Context

This device belongs to the Si827x family of radio frequency coupled isolated gate drivers. It utilizes Skyworks' proprietary RF coupling technology to provide galvanic isolation without optical components. The series is designed to replace traditional optocouplers in high-performance power electronics applications requiring higher speed and reliability.
