SI82395BB-IS1

Isolators - Gate Drivers Overview

The SI82395BB-IS1 is a dual-channel, current-isolated gate driver manufactured by Skyworks Solutions. It features 2500 Vrms isolation voltage and an 8 V Under-Voltage Lock-Out (UVLO). The device operates within a temperature range of -40°C to +125°C and is housed in a 16-pin SOIC-Narrow package. Key electrical parameters include a maximum propagation delay of 40 ns, rise and fall times of 12 ns each, and a power dissipation of 2 W. It is AEC-Q100 qualified for automotive applications.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation between control circuitry and power switches using capacitive coupling technology.
• Features non-inverting logic configuration for straightforward signal transmission.
• Includes under-voltage lock-out protection to ensure reliable operation during low supply conditions.

Isolators - Gate Drivers Applications

• Automotive power electronics systems requiring AEC-Q100 compliance
• Industrial motor drives with high electromagnetic immunity requirements
• Inverter circuits in renewable energy systems

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1 against the manufacturer's latest datasheet to confirm pinout and isolation ratings. Ensure compatibility with the target PCB footprint, specifically the SOIC-Narrow-16 package dimensions. Confirm that the 8 V UVLO threshold aligns with the intended gate drive voltage levels. Check for RoHS compliance status as indicated in official documentation before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when dual isolated channels are required for half-bridge or full-bridge configurations. The 4 A output current capability supports driving medium-power MOSFETs or IGBTs. Consider the 40 ns propagation delay for switching frequency limitations. The wide operating temperature range makes it suitable for harsh environments where standard drivers might fail.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x series of digital isolator gate drivers from Skyworks Solutions. The series is designed to replace traditional optocouplers in high-speed, high-reliability applications. It integrates both the isolation barrier and the gate drive functionality into a single compact package, reducing board space and improving system performance.

Isolators - Gate Drivers Replacement Considerations

Check for direct substitutes within the Si8239x family, such as variants with different UVLO thresholds or isolation voltages. Verify pin-to-pin compatibility if replacing existing designs. Ensure that any alternative maintains the same AEC-Q100 qualification if used in automotive contexts.
