SI8271DBD-IS

Isolators - Gate Drivers Overview

The SI8271DBD-IS is a single-channel current-isolated gate driver from Skyworks Solutions, designed for high-performance switching applications. It features a 2.5 kVRMS isolation voltage and AEC-Q100 automotive qualification. The device operates within a -40°C to +125°C temperature range and utilizes an 8-pin SOIC package. Key electrical parameters include a maximum propagation delay of 75 ns, with rise and fall times of 16 ns and 18 ns respectively. Peak output currents are rated at 1.8 A source and 4 A sink, supporting efficient power stage control.

Isolators - Gate Drivers Feature Summary

High common-mode transient immunity (CMTI) ensures reliable signal transmission in noisy environments
Programmable dead-time functionality prevents shoot-through conditions in bridge configurations
Integrated under-voltage lockout (UVLO) protects against improper operation during low supply states

Isolators - Gate Drivers Applications

Switched-mode power supplies (SMPS)
Solar inverters
Motor control systems

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IS' confirms AEC-Q100 automotive grade qualification and extended temperature range capabilities. Ensure the ordering part number matches the required 8-SOIC surface mount package configuration. Cross-reference the datasheet revision to confirm compatibility with intended system voltage levels and isolation requirements before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when high dV/dt immunity and fast switching speeds are critical for system efficiency. The single-channel architecture suits half-bridge or simple high-side/low-side driving needs. Consider the 1.8A source and 4A sink current capabilities to ensure adequate drive strength for the target MOSFET or IGBT gate capacitance without external buffering.

Isolators - Gate Drivers Part Context

This device belongs to the Si8271 series of silicon-isolated gate drivers. It leverages capacitive coupling technology to provide robust galvanic isolation between control and power domains. The series offers variants with different channel counts and output polarities, but this specific model focuses on single-channel performance with automotive reliability standards.
