SI82391CD-AS

Isolators - Gate Drivers Overview

The SI82391CD-AS is a dual-channel, galvanically isolated gate driver from Skyworks Solutions, designed for automotive applications. It features a 5 kV isolation rating and operates within a temperature range of -40°C to +125°C. The device provides non-inverting outputs with a maximum propagation delay of 40 ns and rise/fall times of 12 ns. It supports input voltages between 2.5 V and 5.5 V, delivering a peak output current of 4 A at an output voltage of 12 V. Power dissipation is rated at 2.1 W, with a quiescent supply current of 7.2 mA. It utilizes a 16-pin SOIC-Wide package.

Isolators - Gate Drivers Applications

• Automotive power electronics systems
• Isolated motor control circuits
• High-side and low-side switching drivers

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'AS' against official Skyworks documentation to confirm it denotes the standard tube packaging variant rather than a reel configuration. Confirm that the component meets all required automotive reliability standards for your specific application environment before finalizing procurement plans.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel isolated driver with automotive certification and high electromagnetic immunity is required. Ensure the system design accommodates the 16-pin SOIC-Wide footprint and that the 5 kV isolation rating aligns with the circuit's voltage requirements.

Isolators - Gate Drivers Part Context

This part belongs to the Si8239x series of isolated gate drivers. It shares functional similarities with other members like the SI82391CD-IS but differs in packaging and specific automotive compliance details. The series is characterized by capacitive coupling technology for reliable signal transmission across isolation barriers.

Isolators - Gate Drivers Replacement Considerations

The SI82391CD-IS is a related variant within the same family. Verify if the IS suffix indicates a different packaging type or specific qualification status compared to the AS version before substitution.
