SI8274AB1-AM1R

Isolators - Gate Drivers Overview

The SI8274AB1-AM1R is a dual-channel digital isolated gate driver from Skyworks Solutions, housed in a 14-LGA (5x5) surface-mount package. It provides galvanic isolation with a 2500 Vrms insulation voltage and supports an operating temperature range of -40°C to +125°C. The device features a maximum propagation delay of 60 ns for the low-to-high path and 75 ns for high-to-low. Output rise and fall times are typically 10.5 ns and 13.3 ns, respectively. It delivers peak output currents of 1.8 A and 4 A, with a supply voltage range of 4.6 V to 30 V.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix AM1R against official Skyworks documentation to confirm tape-and-reel packaging and lead-free status. Ensure compatibility with the 14-LGA footprint during PCB layout. Cross-reference the datasheet for updated RoHS compliance details and handling sensitivity requirements before integration into production designs.

Isolators - Gate Drivers Selection Notes

Select this component when dual-channel isolation with high CMTI is required. Compare performance metrics such as propagation delay and output current against single-channel alternatives if space is constrained. Verify that the 14-LGA package dimensions fit within the mechanical constraints of the target enclosure and assembly process.

Isolators - Gate Drivers Part Context
