SI82396BB-IS1R

Isolators - Gate Drivers Overview

The SI82396BB-IS1R is a dual-channel, galvanically isolated gate driver from the Si8239x series by Skyworks Solutions. It utilizes capacitive coupling technology to provide electrical isolation with an insulation voltage of 2500 Vrms. The device features non-inverting logic and operates within a temperature range of -40°C to +125°C. Key electrical parameters include a maximum propagation delay of 40 ns, rise and fall times of 12 ns each, and a peak output current capability of 4 A. It supports an 8 V Under-Voltage Lock-Out (UVLO) threshold and draws a typical operating supply current of 7.2 mA. The component is housed in a 16-pin SOIC-Narrow package and is qualified under AEC-Q100 standards for automotive reliability.

• Inverter bridge driving in electric vehicles
• Industrial motor drives requiring high noise immunity

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IS1R' confirms the reel packaging variant distinct from tube-packaged versions like 'IS1'. Confirm AEC-Q100 compliance requirements match your automotive quality standards. Ensure the 16-pin SOIC-Narrow footprint aligns with your PCB layout constraints. Check for RoHS compliance documentation if required by your manufacturing regulations.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed switching with robust isolation is required for automotive or industrial applications. The 4 A peak current rating suits medium-power MOSFET and IGBT driving needs. Consider the 12 ns transition times for efficiency optimization in high-frequency converters. Verify that the 2500 Vrms isolation level meets the safety requirements of your specific circuit topology.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x family of isolated gate drivers, which are designed to replace traditional transformer-based solutions. The family offers various isolation voltages and UVLO thresholds, such as the SI82396CD-IS with 12 V UVLO. The SI82396BB-IS1R specifically targets applications needing 8 V UVLO and 2.5 kV isolation, providing a standardized interface for modern power electronics designs.

Isolators - Gate Drivers Replacement Considerations

Direct pin-compatible substitutes within the same series include SI82396BB-IS1 (tube package). For different isolation ratings, consider SI82396CD-IS variants. Always verify package dimensions and thermal characteristics before substituting.
