SI82A40BBE-IS4R

Isolators - Gate Drivers Overview

The SI82A40BBE-IS4R is a single-channel isolated gate driver from Skyworks Solutions, designed for high-voltage power switching applications. It features capacitive coupling technology to provide electrical isolation between the input and output stages. The device supports a supply voltage range of 3 V to 20 V and delivers a peak output current of 1 A. Key electrical parameters include a maximum propagation delay of 55.8 ns, with rise and fall times of 8.3 ns and 8.6 ns respectively. The drain-source on-resistance is specified at 8.58 mOhms. It operates within a temperature range of -40°C to +125°C and is housed in an SSO-8 surface-mount package.

Isolators - Gate Drivers Feature Summary

• Capacitive coupling technology provides robust galvanic isolation without magnetic core saturation limitations.
• Integrated shutdown function allows for precise control over the output state to prevent unintended switching.
• Supports both inverting and non-inverting logic configurations for flexible system integration.

Isolators - Gate Drivers Applications

• Isolated gate driving for IGBTs and MOSFETs in motor drives

• Industrial inverters and AC/DC converters

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS4R against the manufacturer's datasheet to confirm the reel packaging configuration and moisture sensitivity level. Ensure the ordering part number matches the required isolation voltage rating and channel count. Cross-reference the RoHS compliance status and lead time requirements with authorized distributors prior to procurement.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel driver with 6 kV isolation is required for compact designs. Consider the 1 A peak current capability for driving medium-power switches. Evaluate the 55.8 ns propagation delay against system timing constraints. Compare the SSO-8 footprint against available PCB space and thermal management requirements for the target application environment.

Isolators - Gate Drivers Part Context

This part belongs to the SI82xx family of isolated gate drivers from Skyworks Solutions. The series utilizes silicon dioxide (SiO2) based capacitive isolation technology, offering high reliability and long-term stability compared to traditional transformer-based solutions. The SI82A40BBE-IS4R represents a specific variant optimized for single-channel operation with reel packaging for automated assembly processes.

Isolators - Gate Drivers Replacement Considerations

Public confirmed substitute part numbers are not provided in the source documentation. Verify compatibility with alternative Skyworks models such as SI82A40AGC-IS or SI82B40ACE-IS4R by comparing isolation ratings, pinout configurations, and electrical specifications before substitution.
