SI8282EC-ASR

Isolators - Gate Drivers Overview

The SI8282EC-ASR is an automotive-grade, current-isolated gate driver manufactured by Skyworks Solutions. Designed for driving Silicon Carbide (SiC) and IGBT devices, it features a single-channel configuration with inverting and non-inverting outputs. The component operates within a supply voltage range of 2.8 V to 5.5 V and delivers a peak output current of 4 A. It supports high-speed switching with propagation delays up to 50 ns, rise times of 15 ns, and fall times of 20 ns. The device is qualified under AEC-Q100 standards and functions reliably across an extended temperature range from -40°C to +125°C.

Isolators - Gate Drivers Feature Summary
