SID1181KQ

Isolators - Gate Drivers Overview

The SID1181KQ is an 8A single-channel gate driver from the SCALE-iDriver series, designed for automotive IGBT and MOSFET applications. It utilizes capacitive coupling to provide reinforced galvanic isolation of 5000Vrms. The device supports supply voltages between 22V and 28V, with peak output currents of 3.6A (high) and 4A (low). Key electrical parameters include a maximum propagation delay of 340ns (tpLH) and 330ns (tpHL), typical rise/fall times of 465ns/460ns, and a minimum common-mode transient immunity of 50kV/µs. It operates within a temperature range of -40°C to 125°C in an eSOP-R16B package.

Isolators - Gate Drivers Procurement Notes

Verify the specific ordering suffix against official Power Integrations documentation to confirm exact specifications, as suffixes may indicate variations in packaging or tape-and-reel configurations. Ensure compatibility with system voltage requirements and thermal management needs before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Isolators - Gate Drivers Selection Notes

Select this component for applications requiring high isolation voltage and robust noise immunity in automotive environments. The 8A peak drive current suits medium-power SiC devices. Consider the eSOP-R16B footprint for PCB layout constraints. Verify that the input logic levels are compatible with the control MCU or DSP used in the design.

Isolators - Gate Drivers Part Context
