SI8234AB-D-IM1

Isolators - Gate Drivers Overview

The SI8234AB-D-IM1 is a galvanically isolated gate driver from the Si823x series, manufactured by Skyworks Solutions Inc. It features two independent channels configured for high-side and low-side applications within a QFN-14 surface-mount package. The device provides 2.5 kVrms isolation voltage and supports an input voltage range of 4.5 V to 5.5 V with TTL logic compatibility. Key electrical parameters include a maximum propagation delay of 45 ns, rise and fall times of 12 ns each, and a peak output current capability of 4 A. It operates within a temperature range of -40°C to +125°C, dissipates up to 1.2 W of power, and draws a typical operating supply current of 3.5 mA.

Isolators - Gate Drivers Procurement Notes

Verify component authenticity through authorized Skyworks distributors or certified partners. Confirm lot traceability and RoHS compliance status prior to integration. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent package damage during soldering processes.

Isolators - Gate Drivers Selection Notes

Select this part when a compact QFN-14 footprint is required for dual-channel isolation. It is suitable for designs needing 2.5 kVrms isolation rather than higher voltage ratings. Consider the 4 A peak drive strength and 45 ns delay for medium-speed switching applications requiring robust noise immunity.

Isolators - Gate Drivers Part Context

This component belongs to the Si823x family of capacitive isolation gate drivers. It shares architectural similarities with other variants like the SI8234BC-AS1 but differs in packaging (QFN vs SOIC) and specific isolation ratings. The family is designed to replace bulky magnetic isolators in modern power electronics.
