SI8286DC-ASR

Isolators - Gate Drivers Overview

The SI8286DC-ASR is an automotive-grade, current-output isolated gate driver from the Si8286 series by Skyworks Solutions. It features a single channel with galvanic isolation and capacitive coupling technology. The device operates within a supply voltage range of 2.8 V to 5.5 V and delivers a peak output current of 4 A at a maximum voltage of 30 V. Key electrical parameters include a maximum propagation delay of 50 ns, a rise time of 5.5 ns, and a fall time of 8.5 ns. It is qualified under AEC-Q100 standards and housed in a 16-SOIC package.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix ASR corresponds to the Reel packaging configuration when ordering. Confirm that the component meets the required AEC-Q100 automotive qualification standards for your specific application environment. Ensure compatibility with the 16-SOIC footprint during PCB layout. Check for any lead-free or RoHS compliance documentation if required by your manufacturing process.

Isolators - Gate Drivers Selection Notes

Select this component for applications requiring robust isolation between control logic and high-power switches. The 4 A output capability supports direct driving of medium-power devices without external buffers. Consider the 50 ns propagation delay for timing-sensitive switching operations. The wide operating temperature range suits demanding industrial and automotive thermal conditions.

Isolators - Gate Drivers Part Context

This part belongs to the Si828x ISOdriver family, designed as replacements for traditional optocouplers in power electronics. The series emphasizes reduced size, lower power consumption, and enhanced longevity. The SI8286 variant specifically targets single-channel gate driving needs in modern electric vehicle and renewable energy infrastructure systems.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes may include other parts within the Si8286 series with different packaging options such as SI8286DC-AS. Verify pinout compatibility before swapping packages. Ensure replacement components maintain the same AEC-Q100 automotive grade and isolation voltage ratings.
