SI8235BC-D-IS1R

Isolators - Gate Drivers Overview

The SI8235BC-D-IS1R is a dual-channel galvanically isolated gate driver from the Si823x series, manufactured by Skyworks Solutions Inc. It utilizes capacitive coupling technology to provide electrical isolation with a rated voltage of 3750 Vrms. The device features an undervoltage lockout (UVLO) threshold of 8 V and supports output supply voltages ranging from 9.4 V to 24 V. It operates within a temperature range of -40°C to +125°C and is housed in a 16-SOIC package. The component is AEC-Q100 qualified for automotive applications.

Isolators - Gate Drivers Feature Summary

• Capacitive coupling technology provides high electromagnetic immunity and robust signal isolation
• Integrated 8 V undervoltage lockout ensures reliable gate drive operation under varying supply conditions
• Automotive-grade qualification meets AEC-Q100 standards for durability and reliability

Isolators - Gate Drivers Applications

• Industrial motor drives requiring high isolation voltage
• Automotive power electronics systems
• Inverter and converter circuits in renewable energy applications

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix D-IS1R corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 3750 Vrms isolation rating aligns with the safety requirements of the target application circuit. Ensure compatibility with the 16-SOIC footprint during PCB layout verification.

Isolators - Gate Drivers Selection Notes

Select this component when an 8 V UVLO threshold is necessary to prevent partial turn-on of power switches. Compare against the SI8235BD variant if a higher 5000 Vrms isolation rating is required for the system design. Consider the SI8235BB variant if lower peak output current specifications are sufficient for the load.

Isolators - Gate Drivers Part Context

This part belongs to the Si823x family of isolated gate drivers, which are designed for driving IGBTs and MOSFETs in harsh environments. The family offers various isolation ratings and UVLO thresholds to suit different industrial and automotive power conversion needs.

Isolators - Gate Drivers Replacement Considerations

SI8235BD-D-IS1R offers higher 5000 Vrms isolation. SI8235BB-D-IS1R provides similar functionality with potentially different current drive capabilities.
