ACPL-0820-000E

Overview

The ACPL-0820-000E is a high current dual line-driver IC designed for powerline communication applications. It operates on a single 5 V supply and delivers up to 1.5 APP driving current, suitable for driving 7 Ω loads under bridge configurations with low distortion. The device features a 3 MHz gain bandwidth product and -60 dB maximum harmonic distortion. It includes internal load detection and over-temperature shutdown functions reported via a Status pin. Operating within an extended temperature range of -40°C to +85°C, it supports FCC Part 15 and EN50065-1 compliant designs in an SO-8 package.

Feature Summary

• Dual line drivers deliver high current output for differential mode applications
• Integrated thermal shutdown and load detection status reporting
• Transmit enable input allows tri-state disabling to reduce power dissipation

Applications

• Automatic meter reading (AMR)
• Powerline modem transceivers
• General purpose line driver circuits
• Digital-to-analog converter buffers

Procurement Notes

Verify the specific ordering suffix when purchasing. The '-000E' designation indicates a lead-free RoHS 6 compliant product packaged in tubes containing 100 units per tube. Confirm that the required packaging format matches the available options, as reel variants exist with different quantities. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability.

Selection Notes

Select this component for applications requiring high current drive capability at 5 V logic levels. The device is optimized for powerline modem environments where differential signaling is necessary. Designers must account for the 3 MHz bandwidth limitation when selecting modulation schemes. External transient voltage protection components are mandatory to safeguard against mains surges and ensure the total output capacitance remains below 1 nF to prevent oscillations.

Part Context

This part belongs to the ACPL series of line-driver integrated circuits manufactured by Broadcom Limited. It serves as a specialized interface component for coupling digital signals onto power lines. The device replaces older discrete amplifier solutions by integrating biasing, protection, and high-current drive stages into a single compact surface-mount package.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit layouts if considering alternative dual line-driver ICs, particularly regarding pinout definitions and thermal resistance characteristics.
