ACPL-P345-560E

Overview

The Broadcom ACPL-P345-560E is a high-speed logic output optocoupler designed for gate driver applications. It features a single channel with a push-pull output stage capable of delivering up to 1 A of continuous output current. The device utilizes an AlGaAs LED optically coupled to an integrated circuit, providing 3750 Vrms isolation voltage. Key electrical parameters include a typical rise time of 8 ns and fall time of 8 ns, with a maximum power dissipation of 550 mW. It operates within a temperature range of -40°C to +105°C and is housed in a SOIC-6 package.

Feature Summary

• Integrated push-pull output stage for direct gate drive capability
• High common mode transient immunity for noisy environments
• Optical coupling via AlGaAs LED ensures signal integrity

Applications

• Silicon Carbide (SiC) MOSFET gate driving
• Gallium Nitride (GaN) transistor switching
• Industrial motor control systems

Procurement Notes

Verify the specific suffix '560E' against the manufacturer's latest datasheet to confirm pinout compatibility and insulation ratings. Ensure the ordering quantity aligns with standard reel packaging requirements. Cross-reference the RoHS compliance status and lead times directly with authorized distributors or the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when high-speed switching and robust isolation are required for wide-bandgap semiconductors. The 1 A output current supports direct driving of medium-power SiC and GaN devices without external buffers. Consider the SOIC-6 package constraints and thermal dissipation limits relative to the application's ambient temperature and duty cycle requirements.

Part Context

This part belongs to the ACPL-x345 series, which includes variants like the ACPL-P345-500E. These devices are engineered specifically for the demanding requirements of modern power electronics, offering enhanced performance over standard optocouplers. The series integrates advanced circuitry to minimize propagation delay variations and improve reliability in high-voltage switching scenarios.

Replacement Considerations

Check for ACPL-P345-500E as a potential variant within the same family, noting that suffix differences may indicate changes in packaging or specific qualification standards rather than functional alterations.
