HCPL-4506#560

Logic Output Optoisolators Overview

The HCPL-4506 is a single-channel logic output optocoupler from Broadcom, designed for gate drive interfaces. It features an open collector output with Schottky clamping and a built-in 20kΩ pull-up resistor. Key electrical parameters include a maximum propagation delay of 550ns (tpLH) and 400ns (tpHL), supporting data rates up to 1 Mbps. The device offers a minimum common-mode transient immunity of 15kV/µs and an isolation voltage of 3750 Vrms. Operating temperatures range from -40°C to +100°C, with a supply voltage range of 4.5V to 30V.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., 000E, 560E) against the datasheet to confirm package type and insulation voltage ratings. Ensure the selected variant matches the required isolation standards such as UL, VDE, or CSA certifications for the target application safety requirements.

Logic Output Optoisolators Selection Notes

Select this component when high-speed signal isolation is required for power electronics. The integrated pull-up resistor makes it suitable for direct IPM interfacing without additional components. Consider the 15kV/µs CMTI rating for noisy environments typical in motor drives and industrial inverters.

Logic Output Optoisolators Part Context

The HCPL-4506 belongs to Broadcom's HCPL series of logic output optocouplers. It is specifically engineered for power module and gate drive interface applications, distinguishing itself through integrated circuitry that minimizes external component count while maintaining high reliability and fast switching performance.

Logic Output Optoisolators Replacement Considerations

Public confirmed substitutes include HCNW4506 and HCPL-J456. Verify compatibility regarding LED material (AlGaAs vs GaAsP) and insulation voltage ratings before substitution.
