SI8283EC-ISR

Isolators - Gate Drivers Overview

The SI8283EC-ISR is a single-channel digital isolated gate driver utilizing capacitive coupling technology. It provides galvanic isolation with a rated voltage of 5000Vrms and supports a peak output current of 4A. The device operates within an output supply voltage range of 2.8V to 5.5V and features a minimum common-mode transient immunity of 35kV/µs. Propagation delays are limited to 50ns for both high-to-low and low-to-high transitions, with a maximum pulse width distortion of 5ns. Typical rise and fall times are 5.5ns and 8.5ns respectively. It is housed in a 24-SOIC package and certified to AEC-Q100 standards for automotive applications.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'EC' against official Skyworks documentation to confirm exact electrical characteristics and pinout compatibility. Ensure the 24-SOIC package dimensions match the target PCB footprint. Confirm that the capacitive coupling technology aligns with system noise immunity requirements. Check for valid AEC-Q100 certification if automotive deployment is intended. Validate operating temperature ranges against environmental constraints.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed isolation with low propagation delay is required for power switching applications. The 4A peak drive capability suits medium-power IGBT and MOSFET gates. Consider the 24-SOIC package for surface-mount assembly needs. Verify input logic levels and output supply voltages match the controller and power stage specifications. Evaluate thermal management requirements given the -40°C to 125°C operating range.

Isolators - Gate Drivers Part Context

The SI8283EC-ISR belongs to the SI82xx series of digital isolators from Skyworks Solutions. This family utilizes proprietary capacitive coupling technology to replace traditional magnetic isolation methods. The series offers various channel configurations and drive strengths tailored for industrial and automotive markets.
