HCPL-4506#500

Logic Output Optoisolators Overview

The HCPL-4506#500 is a single-channel logic output optocoupler from Broadcom Limited, housed in an 8-pin PDIP package. It features an open collector output with Schottky clamping and a built-in 20kΩ pull-up resistor. The device supports a data rate of 1 Mbps with a typical rise/fall time of 5ns. Key electrical parameters include a maximum propagation delay of 650ns, a current transfer ratio ranging from 44% to 90%, and an isolation voltage of 3750Vrms. It operates within a temperature range of -40°C to +100°C.

Logic Output Optoisolators Feature Summary

• Minimizes propagation delay differences to reduce switching dead-time
• Provides high common-mode transient immunity

Logic Output Optoisolators Applications

• Isolated IGBT and MOSFET gate driving
• Smart Power Module (IPM) interface circuits
• AC and brushless DC motor drivers
• Industrial inverter systems

Logic Output Optoisolators Procurement Notes

Verify the specific suffix #500 against official datasheets to confirm packaging details, as suffixes often denote reel or tube quantities rather than functional changes. Ensure compatibility with RoHS standards and required safety certifications such as UL, VDE, or CSA for your target market. Cross-reference pinout configurations to match existing PCB layouts.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside robust noise immunity. The integrated pull-up resistor reduces external component count in IPM applications. Consider the 3750Vrms isolation rating for primary-side sensing or control loops. Verify that the 15mA continuous output current meets the load requirements of the driven gate driver stage.

Logic Output Optoisolators Part Context

This part belongs to the HCPL series of logic output optocouplers designed for industrial and automotive power electronics. It utilizes a GaAsP LED for efficient optical transmission. The series is characterized by fast response times and high reliability, making it suitable for demanding environments where signal integrity and electrical isolation are critical for system safety.

Logic Output Optoisolators Replacement Considerations

Direct substitutes include HCPL-4506-000E and HCPL-J456-000E. Note that HCPL-J456 variants utilize an AlGaAs LED instead of GaAsP, which may affect aging characteristics. HCNW4506 is another alternative within the same family. Always verify pin compatibility and thermal performance before substitution.
