SI823H3BB-IS1R

Isolators - Gate Drivers Overview

The SI823H3BB-IS1R is a dual-channel isolated gate driver from the Skyworks Si823Hx series, designed for high-speed switching applications. It features a 2500 Vrms isolation rating and operates within a supply voltage range of 3 V to 5.5 V. The device provides a peak output current of 6 A with propagation delays of 40 ns maximum. It utilizes capacitive coupling technology for signal transmission across the isolation barrier. The component is housed in a 16-pin SOIC package and is qualified under AEC-Q100 standards for automotive reliability.

Isolators - Gate Drivers Feature Summary

• Capacitive coupling technology ensures high electromagnetic immunity and robust signal integrity
• Dual-channel configuration supports independent high-side and low-side driving
• Automotive qualification ensures reliability in demanding operational environments

Isolators - Gate Drivers Applications

• Motor control systems requiring galvanic isolation

• Automotive inverter and converter topologies

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IS1R' confirms the reel packaging format distinct from tube variants. Confirm the AEC-Q100 qualification status aligns with target application requirements. Ensure the 2500 Vrms isolation rating meets system safety standards. Validate the 6 A output capability against load specifications. Check for RoHS compliance documentation prior to integration.

Isolators - Gate Drivers Selection Notes

Select this variant when reel packaging is required for automated assembly processes. Choose based on the 6 A drive strength suitable for medium-power MOSFETs or IGBTs. Consider the 40 ns propagation delay for timing-sensitive designs. Verify compatibility with 3 V to 5.5 V logic inputs. Ensure the 16-pin SOIC footprint fits the PCB layout constraints.

Isolators - Gate Drivers Part Context

This part belongs to the Si823Hx family of isolated gate drivers from Skyworks Solutions. The family leverages silicon dioxide (SiO2) capacitive isolation technology. Variants differ primarily by insulation ratings, output current capabilities, and packaging formats such as tubes or reels. This specific model represents a mid-range performance option within the series.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include other Skyworks Si823Hx variants with matching 6 A output and 16-pin SOIC packages. Cross-brand replacements require verifying equivalent isolation voltage, drive current, and package dimensions. Ensure functional pinouts match to avoid redesign efforts.
