SI8271GB-IS

Isolators - Gate Drivers Overview

The SI8271GB-IS is a single-channel isolated gate driver from Skyworks Solutions, utilizing silicon-based isolation technology to provide 2.5 kVrms insulation voltage. It operates within an input voltage range of 2.5 V to 5.5 V and supports TTL logic inputs. The device features a maximum propagation delay of 75 ns, with rise and fall times of 16 ns and 18 ns respectively. It delivers a peak output current of 4 A and functions reliably across a temperature range of -40°C to +125°C. Packaged in an SOIC-8 surface-mount format, it includes under-voltage lockout (UVLO) and is qualified to AEC-Q100 standards for automotive applications.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'GB' against the manufacturer's latest datasheet to confirm pinout and electrical specifications match the design requirements. Ensure compliance with RoHS directives and check for AEC-Q100 qualification status if automotive usage is intended. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly to prevent package damage during manufacturing processes.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel driver with robust 2.5 kV isolation is required. It is suitable for designs needing fast switching speeds with minimal propagation delay. Consider the SOIC-8 package size for space-constrained PCB layouts. Verify that the 4 A output current capability meets the gate charge requirements of the target power switches.

Isolators - Gate Drivers Part Context

This part belongs to the Si8271 series of isolated gate drivers from Skyworks Solutions.
