SI823H6BB-IM1R

Isolators - Gate Drivers Overview

The SI823H6BB-IM1R is a dual-channel isolated gate driver from Skyworks Solutions, utilizing silicon dioxide (SiO2) capacitive coupling technology for signal and power isolation. It features a 5 kVrms isolation rating and operates within an extended temperature range of -40°C to +125°C. The device provides independent high-current outputs capable of driving MOSFETs and IGBTs with peak currents up to 6 A. It includes integrated undervoltage lockout (UVLO) circuits on both the source and drain sides to prevent improper switching during low-voltage conditions. The component is housed in a compact 14-lead DFN package.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IM1R' against the manufacturer's official datasheet to confirm the 14-lead DFN package and reel packaging configuration. Ensure that the required isolation voltage ratings and operating temperature ranges align with the target application's environmental specifications before finalizing procurement orders.

Isolators - Gate Drivers Selection Notes

Select this component when high-density isolation is required for power stages. The dual-channel design supports half-bridge and full-bridge applications efficiently. Consider the 6 A output current capability for medium-power devices. Verify compatibility with the control logic voltage levels and ensure adequate PCB layout for the capacitive isolation barrier.
