SI8232BC-D-IS1R

Isolators - Gate Drivers Overview

The SI8232BC-D-IS1R is a dual isolated gate driver from the Si823x series by Skyworks Solutions. It features two independent drivers in a single package with 3.75 kVrms insulation voltage and an 8 V UVLO threshold. The device operates within a temperature range of -40°C to +125°C, dissipating up to 1.2 W. Key electrical parameters include a maximum propagation delay of 45 ns, rise time of 20 ns, and fall time of 20 ns. It utilizes a SOIC-Narrow-16 surface-mount package and is supplied in a reel format.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1R indicates reel packaging when ordering. Confirm the 3.75 kVrms isolation rating and 8 V UVLO specification match the design requirements. Ensure the SOIC-Narrow-16 footprint is compatible with the PCB layout. Cross-reference the manufacturer part number with official Skyworks documentation to avoid confusion with similar variants like SI8232AC or SI8232BB.

Isolators - Gate Drivers Selection Notes

Select this component for designs requiring dual-channel isolation with high common-mode transient immunity. The 8 V UVLO threshold suits applications needing robust under-voltage lockout protection. Consider the 45 ns propagation delay for switching frequency requirements. The wide operating temperature range supports harsh industrial environments. Verify compatibility with input logic levels before integration.
