SI82520BB-IM1

Isolators - Gate Drivers Overview

The SI82520BB-IM1 is a galvanically isolated gate driver from the Si8252x series, manufactured by Skyworks Solutions Inc. It features a single-channel configuration with high-side and low-side outputs in a 14-DFN (5x5 mm) package. The device operates within a supply voltage range of 4.5 V to 20 V and supports an operating temperature range of -40°C to +125°C. It provides peak output currents of 4 A for the high side and 6 A for the low side, with typical rise and fall times of 12 ns.

Isolators - Gate Drivers Feature Summary

• Provides galvanic isolation between control circuitry and power switches using capacitive coupling technology.
• Integrates both high-side and low-side driver channels for half-bridge applications.
• Features automotive qualification under the AEC-Q100 standard for reliability.

Isolators - Gate Drivers Applications

• Automotive motor control systems
• Industrial inverters and converters
• High-voltage switching circuits

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IM1 against official Skyworks documentation to confirm pinout and package dimensions. Confirm current production status as end-of-life or active, given potential discontinuation notices for similar variants. Ensure compatibility with required isolation voltage ratings for the target application environment.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel isolated driver with asymmetric peak current capabilities is required. The 14-DFN package suits space-constrained designs. Verify that the 2.5 kVrms isolation rating meets system safety requirements. Consider thermal dissipation limits at maximum load conditions within the specified temperature range.

Isolators - Gate Drivers Part Context

This part belongs to the Si8252x family of isolated gate drivers. It shares architectural similarities with other members like the SI82520BD-AS3 but differs in packaging and specific electrical characteristics. The family targets robust industrial and automotive environments requiring reliable signal transmission across isolation barriers.

Isolators - Gate Drivers Replacement Considerations

Official substitutes include SI82520BD-AS3 and SI82521BB-IM1. Verify pin compatibility and electrical specifications before substitution. Cross-reference datasheets for differences in isolation voltage and package type.
