SI8752AB-IS

Isolators - Gate Drivers Overview

The SI8752AB-IS is an isolated FET driver from Skyworks Solutions, featuring a diode emulation input for custom solid-state relay configurations. It utilizes capacitive coupling technology to provide robust isolation with a 2.5 kVrms rating. The device operates within a supply voltage range of 2.25 V to 5.5 V and supports temperatures from -40°C to +105°C. It is housed in an SOIC-8 package and holds AEC-Q100 qualification.

Isolators - Gate Drivers Feature Summary

• Integrates diode emulation input functionality to simplify the creation of custom solid-state relay topologies.
• Employs capacitive coupling technology to deliver high-reliability signal isolation between input and output stages.
• Provides flexible output configuration capable of driving both AC and DC load setups effectively.

Isolators - Gate Drivers Applications

• Custom solid-state relay (SSR) design
• Isolated switching for AC loads
• Isolated switching for DC loads

Isolators - Gate Drivers Procurement Notes

Verify that the specific suffix matches the required isolation and input type specifications. Confirm AEC-Q100 automotive qualification status if applicable to the target environment. Ensure the SOIC-8 package dimensions align with the PCB footprint requirements. Check moisture sensitivity levels for proper storage and reflow soldering procedures.

Isolators - Gate Drivers Selection Notes

Select this component when a diode emulation input is specifically required for SSR applications rather than standard digital pin control. Compare against the SI8751 series if digital CMOS input logic is preferred instead. Consider the 2.5 kVrms isolation barrier strength relative to system safety standards. Evaluate the operating temperature range against the intended environmental conditions.

Isolators - Gate Drivers Part Context

This part belongs to the Si875x family of isolated FET drivers designed for relay replacement applications. It combines strong isolation technology with efficient gate drive capabilities. The series offers flexibility through different input types, including diode emulation and digital control options.

Isolators - Gate Drivers Replacement Considerations

SI8751AB-IS serves as a functional alternative within the same family, differing primarily by offering digital CMOS pin control inputs instead of diode emulation functionality. Both parts share similar isolation characteristics and package options.
