SI8235BB-D-IS1

Isolators - Gate Drivers Overview

The SI8235BB-D-IS1 is a dual-channel, galvanically isolated gate driver from Skyworks Solutions Inc., utilizing capacitive coupling technology. It provides 2500Vrms isolation voltage and supports an output supply voltage range of 9.4V to 24V. The device features peak output currents of 2A for the high-side and 4A for the low-side channels. It operates within a temperature range of -40°C to 125°C and carries AEC-Q100 automotive qualification. The component is housed in a 16-SOIC package with a maximum propagation delay of 60ns.

Isolators - Gate Drivers Feature Summary

• Capacitive coupling technology enables high electromagnetic immunity and reliable signal transmission across the isolation barrier.
• Dual-channel configuration allows independent control of high-side and low-side power switches.
• Automotive-grade qualification ensures compliance with AEC-Q100 standards for durability and performance.
• Integrated under-voltage lockout (UVLO) protects against improper operation during low supply conditions.

Isolators - Gate Drivers Applications

• Motor drive systems requiring isolated gate control
• Inverter circuits in electric vehicle powertrains
• Industrial motor controllers needing high noise immunity

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'D-IS1' matches the required isolation voltage and package variant. Confirm AEC-Q100 certification status if automotive application is mandatory. Check datasheet for latest pinout and thermal specifications before integration. Ensure ordering quantity aligns with manufacturer standard packaging requirements.

Isolators - Gate Drivers Selection Notes

Select this part when 2500Vrms isolation is sufficient for the system design. Compare peak current capabilities against load requirements. Consider the 16-SOIC footprint for PCB layout constraints. Evaluate thermal dissipation needs given the operating temperature range and power consumption characteristics.

Isolators - Gate Drivers Part Context

This component belongs to the Si823x family of isolated gate drivers. It complements other variants like SI8235BD-D-ISR which offers higher 5000Vrms isolation. The family shares similar functional architectures but differs in isolation ratings and packaging options to suit various industrial and automotive applications.

Isolators - Gate Drivers Replacement Considerations

SI8235BB-D-IS is a direct substitute with identical electrical specifications. SI8235BD-D-ISR offers higher isolation voltage but requires verification of compatibility with existing board layouts and regulatory approvals.
