HCPL-0900-500

Overview

The HCPL-0900-500 is a general-purpose digital isolator manufactured by Broadcom Limited. It features magnetic coupling technology for signal transmission across an isolation barrier. The device operates with a single channel and supports unidirectional data flow. Key electrical specifications include a data rate of 100 MBd, an insulation voltage of 2500 Vrms, and a common-mode transient immunity (CMTI) of 15 kV/µs. It functions within a supply voltage range of 3 V to 5.5 V. The component is housed in an 8-SOIC package with a width of 3.90 mm.

Feature Summary

• Utilizes magnetic coupling for galvanic isolation between input and output circuits
• Provides high common-mode transient immunity to prevent false triggering in noisy environments
• Supports unidirectional signal transmission for single-channel applications
• Operates on standard logic supply voltages without requiring external bias supplies

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power electronics control circuits with high-voltage noise environments
• General-purpose digital isolation in embedded systems

Procurement Notes

Verify the current lifecycle status before procurement as this part may be discontinued or subject to limited availability. Confirm that the 8-SOIC package dimensions match your PCB footprint requirements. Ensure the 2500 Vrms isolation rating meets your specific safety standards. Check for RoHS compliance documentation if required by your manufacturing regulations. Validate that the 100 MBd data rate is sufficient for your application's timing constraints.

Selection Notes

Select this component when a single-channel, unidirectional isolator is required. Consider the 15 kV/µs CMTI rating for applications with rapid voltage transients. The 3 V to 5.5 V operating range allows compatibility with various logic families. Evaluate the 8-SOIC package size against available board space. Compare the 100 MBd speed against higher-speed alternatives if data throughput is critical.
