ACPL-P483-000E

Overview

The ACPL-P483-000E is a logic output optoisolator from Broadcom Limited, designed for high-speed digital signal isolation. It integrates an AlGaAs LED and a photodetector with a built-in Schmitt trigger to provide fast switching capabilities. The device features a push-pull, totem pole output configuration suitable for inverting applications. Key electrical parameters include a maximum continuous output current of 50 mA, a forward voltage of 1.5 V, and a reverse voltage rating of 5 V. It offers an insulation voltage of 3750 Vrms and supports a data rate of 1 MB/s. The component operates within a temperature range of -40°C to +105°C and is housed in a 6-SOIC stretched package.

Feature Summary

• Integrates an AlGaAs LED and photodetector with a built-in Schmitt trigger for noise immunity
• Features a push-pull, totem pole output configuration for fast switching performance
• Provides high common-mode transient immunity (CMTI) of 30 kV/µs
• Designed for IPM interface applications with inverting logic output

Applications

• Industrial power module interfaces
• Automotive electronic control units
• High-speed digital signal isolation circuits

Procurement Notes

Verify the specific suffix and manufacturer documentation to confirm the exact pinout and electrical characteristics, as variations may exist between different production batches or regional specifications. Ensure compatibility with the target PCB footprint, specifically the 6-SOIC stretched package dimensions. Cross-reference the datasheet for thermal dissipation requirements under maximum operating conditions to prevent overheating during sustained operation.

Selection Notes

Select this component when high-speed isolation with inverting logic functionality is required. The integrated Schmitt trigger enhances noise rejection in electrically noisy environments. Consider the 3750 Vrms insulation rating for safety-critical applications. The push-pull output drives loads directly, reducing external component count compared to open-collector alternatives. Verify that the 1 MB/s data rate meets the system timing requirements.

Part Context

The ACPL-P483-000E belongs to the ACPL series of fast-speed optocouplers manufactured by Broadcom Limited. This series is engineered for robust performance in industrial and automotive sectors. The part is distinct from non-inverting variants like the ACPL-P484 due to its internal logic inversion and Schmitt trigger integration. It serves as a critical interface component for protecting low-voltage control circuits from high-voltage power stages.
