SI823H3CB-IM1

Isolators - Gate Drivers Overview

The SI823H3CB-IM1 is a dual-channel isolated gate driver from Skyworks Solutions, designed for automotive applications. It features high-voltage isolation of 2.5 kVrms and operates within an extended temperature range of -40°C to +125°C. The device utilizes silicon dioxide (SiO2) technology for reliable signal transmission across the isolation barrier. It supports both high-side and low-side configurations with non-inverting logic inputs. The component is housed in a QFN-14 package suitable for surface-mount assembly.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation between control circuitry and power switches using SiO2 dielectric technology
• Supports independent high-side and low-side driver channels for half-bridge topologies
• Includes under-voltage lockout (UVLO) mechanisms to prevent improper switching during power transitions

Isolators - Gate Drivers Applications

• Automotive motor control systems
• Inverter bridge driving in electric vehicle powertrains
• Industrial motor drive interfaces

Isolators - Gate Drivers Procurement Notes

Verify current availability status as distribution channels may indicate limited stock or discontinuation notices. Confirm RoHS compliance and AEC-Q100 qualification through official Skyworks documentation before integration. Ensure proper handling procedures are followed due to moisture sensitivity classification associated with the QFN package type.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated driver with 2.5 kVrms isolation is required for automotive environments. The QFN-14 package offers a compact footprint compared to SOIC alternatives. Consider the specific propagation delay and output current capabilities relative to the target MOSFET or IGBT requirements.

Isolators - Gate Drivers Part Context

This part belongs to the Si823Hx family of isolated gate drivers manufactured by Skyworks Solutions. The series is characterized by its use of planar transformer and SiO2 insulation technologies to achieve high reliability and fast switching speeds. The 'IM1' suffix typically denotes the specific pin-out and packaging configuration within the broader product line.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include other variants within the Si823Hx family such as the SI823H5BB-IM1 or SI823H6CB-IS1, provided they match the required isolation voltage and package dimensions. Verify that any replacement maintains the same AEC-Q100 automotive qualification and thermal performance characteristics.
