SI8274AB4D-IM1R

Isolators - Gate Drivers Overview

The SI8274AB4D-IM1R is a single-channel, galvanically isolated gate driver from the Skyworks SI827x series. It features high common-mode transient immunity (CMTI) of 200 kV/µs and latch-up immunity of 400 kV/µs. The device supports PWM input with deglitching functionality and includes under-voltage lockout (UVLO). It operates within a supply voltage range of 4.6 V to 30 V and provides peak output currents of 1.8 A for low-side and 4 A for high-side configurations. Key timing parameters include a maximum propagation delay of 105 ns, a rise time of 16 ns, and a fall time of 18 ns. The component is housed in a 14-LGA package and is rated for operation between -40°C and +125°C.

Isolators - Gate Drivers Procurement Notes

Verify current availability status as this part number may be subject to discontinuation or lifecycle changes. Confirm that the specific ordering suffix matches the required package variant and tape-and-reel configuration. Cross-reference the manufacturer's official datasheet for any recent product change notifications (PCN) regarding pinout or electrical parameter updates before finalizing procurement plans.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel isolated driver with high CMTI is required. Ensure the application demands PWM input compatibility rather than dual digital inputs. Verify that the 14-LGA package fits the PCB layout constraints. Compare against other SI827x variants if dual-channel or different UVLO thresholds are needed.

Isolators - Gate Drivers Part Context

This device belongs to the SI827x family of capacitive isolation gate drivers. It shares architectural similarities with models like the SI8274GB4D but differs in channel count and specific input interface capabilities. The 'IM1R' suffix indicates a 14-LGA surface-mount package supplied in a tape-and-reel format for automated assembly processes.

Isolators - Gate Drivers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Check for direct replacements within the SI827x family, such as the SI8274AB4D-IM1, noting differences in packaging or lifecycle status.
