SI8275DB-AM1R

Isolators - Gate Drivers Overview

The SI8275DB-AM1R is an automotive-grade, galvanically isolated gate driver from the Skyworks Si827x series. It features a dual-channel configuration housed in a 16-pin SOIC package with surface-mount installation. The device provides high common-mode transient immunity and includes under-voltage lockout (UVLO) for reliable operation. Key electrical parameters include a maximum propagation delay of 75 ns, rise time of 16 ns, and fall time of 18 ns. It operates within a temperature range of -40°C to +125°C, dissipates up to 1.2 W of power, and supports input voltages between 2.5 V and 5.5 V.

Isolators - Gate Drivers Procurement Notes

Verify component authenticity through authorized Skyworks distributors or certified partners. Confirm that the specific part number matches the required automotive grade specifications. Check for valid RoHS compliance documentation and ensure the package type aligns with PCB design requirements. Validate manufacturing dates against project timelines to avoid obsolescence risks.

Isolators - Gate Drivers Selection Notes

Select this component when automotive certification and high CMTI are mandatory. Compare propagation delays and output current capabilities against other Si827x variants if different packaging or thermal characteristics are needed. Ensure the 16-pin SOIC footprint fits the target assembly constraints. Verify compatibility with the system's logic voltage levels before integration.

Isolators - Gate Drivers Part Context

This device belongs to the Si827x family of isolated gate drivers, designed for high-performance power electronics. The series utilizes silicon dioxide isolation technology to provide galvanic separation between control and power sides. The DB suffix indicates the specific 16-pin SOIC package variant, distinguishing it from DFN or other form factors within the same functional family.
