SI8751AB-IS

Isolators - Gate Drivers Overview

The SI8751AB-IS is an isolated FET gate driver manufactured by Skyworks Solutions Inc. It features a digital CMOS input isolator with a 2.5 kV isolation rating. The device operates within a supply voltage range of 2.25 V to 5.5 V and supports a maximum operating temperature of +105°C, with a minimum of -40°C. It is housed in an SOIC-8 surface-mount package and holds AEC-Q100 qualification for automotive reliability.

Isolators - Gate Drivers Feature Summary

• Integrates strong isolation technology with solid-state relay FET driver capabilities
• Provides flexible output support for driving both AC and DC load configurations
• Utilizes digital CMOS pin control input for simplified custom SSR configuration

Isolators - Gate Drivers Applications

• Custom solid-state relay (SSR) configurations
• Isolated switching applications requiring efficient FET gate drive
• AC or DC load driving systems

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'IS' corresponds to the SOIC-8 tube packaging format as listed in distributor specifications. Confirm that the AEC-Q100 qualification status meets your project's automotive reliability requirements. Ensure the 2.5 kV isolation voltage aligns with your system's safety standards. Cross-reference the manufacturer part number against official Skyworks documentation to avoid counterfeit components.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel isolated gate driver with digital input is required. It is suitable for designs needing robust isolation between control and power stages. Consider the Si8752 variant if diode emulation functionality is preferred over pin control. Ensure the SOIC-8 footprint fits the PCB layout constraints and thermal management needs.

Isolators - Gate Drivers Part Context

The SI8751AB-IS belongs to the Si8751/Si8752 series of isolated FET drivers from Skyworks Solutions. This family combines high-performance isolation with gate drive strength. The Si8751 specifically offers pin control inputs, distinguishing it from the diode emulation-based Si8752. Both are designed for creating compact, reliable solid-state relay solutions.

Isolators - Gate Drivers Replacement Considerations

The Si8752AB-IS serves as a functional alternative within the same series, offering diode emulation input instead of digital pin control. Both share similar isolation ratings and package options. Verify input logic compatibility when substituting, as the control mechanism differs between the two models.
