HCPL-090J-500E

Overview

The HCPL-090J-500E is a quad digital isolator from Broadcom Limited, utilizing Giant Magnetoresistive (GMR) technology for magnetic coupling. It provides four independent channels with unidirectional signal transmission in a 16-pin SOIC-Narrow package. The device operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 100 MBd. Key electrical specifications include a propagation delay of 12 ns to 15 ns, an isolation voltage of 2500 Vrms, and a common-mode transient immunity of 15 kV/µs. It functions reliably across an industrial temperature range of -40°C to +100°C.

Feature Summary

• Employs symmetric magnetic coupling via GMR technology for high-speed signal isolation
• Provides excellent transient immunity against common-mode noise spikes
• Features low power consumption suitable for energy-efficient designs
• Offers four isolated channels in a compact surface-mount package

Applications

• Industrial automation systems requiring galvanic isolation
• Power electronics gate drive circuits
• Medical equipment signal interfaces

Procurement Notes

Verify the specific suffix '500E' to ensure compliance with RoHS directives and lead-free manufacturing standards. Confirm that the SOIC-16 package dimensions match your PCB footprint requirements. Check the latest datasheet for any updates regarding operating conditions or recommended soldering profiles before finalizing procurement orders.

Selection Notes

Select this component when high common-mode transient immunity is critical for system stability. The GMR technology offers superior performance compared to traditional capacitive isolators in noisy environments. Ensure the required data rate does not exceed 100 MBd and that the supply voltage remains within the 3 V to 5.5 V range for optimal operation.

Part Context

This part belongs to the HCPL series of digital isolators manufactured by Broadcom Limited. The series utilizes proprietary magnetic coupling technology to provide robust isolation between circuit sections. The HCPL-090J variant specifically denotes a quad-channel configuration designed for general-purpose high-speed isolation applications.

Replacement Considerations

Direct substitutes may include other Broadcom GMR isolators from the same family. Verify channel count, package type, and isolation voltage ratings when considering alternatives from different manufacturers.
