SI8275AB-IS1

Isolators - Gate Drivers Overview

The SI8275AB-IS1 is a dual-channel, galvanically isolated gate driver manufactured by Skyworks Solutions Inc. It operates within an input voltage range of 2.5 V to 5.5 V and provides a 2.5 kVrms isolation rating. The device features a maximum propagation delay of 75 ns, with rise and fall times of 16 ns and 18 ns respectively. It supports a working supply current of 10 mA and delivers an output current of 4 mA at an output voltage of 3 V. Designed for industrial applications, it offers high CMTI, low latency, and skew characteristics.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS1 against official Skyworks documentation to confirm pinout and electrical specifications. Ensure compatibility with target PCB footprint and thermal requirements. Confirm availability through authorized distributors as stock levels vary. Validate that the component meets all necessary safety certifications for the intended application environment.

Isolators - Gate Drivers Selection Notes

Select this component when dual-channel isolation is required with high-speed switching capabilities. Consider the 2.5 kVrms isolation barrier for safety-critical designs. Evaluate the 75 ns propagation delay against system timing constraints. Ensure the 4 mA output current is sufficient for driving the target gate capacitance without excessive delay.

Isolators - Gate Drivers Part Context

This part belongs to the Si8275 series of isolated gate drivers from Skyworks Solutions. It is designed for robust performance in electrically noisy environments. The series emphasizes low latency and skew, making it suitable for precision control applications requiring reliable signal transmission across isolation barriers.

Isolators - Gate Drivers Replacement Considerations

Check for direct substitutes within the Si8275 family or compatible single-channel drivers if only one channel is needed. Verify pin-to-pin compatibility before substitution. Review datasheets for differences in UVLO thresholds or output drive strength.
