SI82F99BBE-IS3

Isolators - Gate Drivers Overview

The SI82F99BBE-IS3 is a dual-channel isolated gate driver from the Si82Fx family, manufactured by Skyworks Solutions Inc. It features silicon dioxide (SiO2) isolation technology with a 6 kV RMS insulation rating and supports SelVCD standards. The device operates within a supply voltage range of 3 V to 20 V on the input side and provides output voltages up to 30 V. It delivers peak drive currents of 2.5 A for both high-side and low-side channels. Key electrical parameters include a maximum propagation delay of 8 ns, rise time of 16 ns, and fall time of 19 ns. It functions in non-inverting mode with a shutdown feature, operating reliably between -40°C and +125°C.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix BE against official Skyworks documentation to confirm pinout and functional configuration. Ensure the selected package variant matches the required PCB footprint. Confirm that the 6 kV isolation rating meets the safety requirements of the target application environment. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Isolators - Gate Drivers Selection Notes

Select this component when high common-mode transient immunity and compact form factor are required. The dual-channel architecture simplifies half-bridge designs compared to single-channel alternatives. Consider the 2.5 A drive strength sufficient for medium-power MOSFETs or IGBTs. Evaluate the thermal performance within the SOIC-14 package for the expected duty cycle and ambient conditions.

Isolators - Gate Drivers Part Context

This part belongs to the Si82Fx series of isolated gate drivers, which utilize Skyworks' proprietary capacitive isolation technology. The series is designed to replace traditional magnetic isolators in space-constrained applications. The SI82F99BBE-IS3 specifically targets applications requiring robust protection against voltage spikes and rapid switching transients in power electronics systems.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes may include other parts within the Si82Fx family with matching isolation ratings and drive currents. Verify pin-to-pin compatibility before substitution. Alternative technologies such as magnetic isolators may offer different isolation characteristics but require layout adjustments.
