ACPL-0820-500E

Overview

The ACPL-0820-500E is a high-current dual line-driver IC manufactured by Broadcom Limited. It operates on a single 5 V supply and delivers up to 1.5 APP driving current, making it suitable for differential mode applications like powerline modems. 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. Packaged in an SO-8 surface mount format with a Tape & Reel quantity of 1500 per reel, it supports operation from -40°C to +85°C.

Feature Summary

• Dual line drivers capable of delivering 1.5 APP driving current under bridge configuration
• Integrated thermal shutdown and load detection status reporting
• Transmit enable input allows disabling outputs to reduce power dissipation
• Supports differential or single-ended to differential connections

Applications

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

Procurement Notes

Verify the specific ordering suffix '-500E' to confirm the component is supplied in a Tape & Reel packaging format containing 1500 units per reel. Ensure the RoHS compliant option is selected if lead-free requirements are mandatory for the assembly process. Cross-reference the manufacturer part number against authorized distributor catalogs to confirm availability and correct package type before finalizing procurement orders.

Selection Notes

Select this component when a high-current output stage is required for powerline communication systems operating within a 5 V supply range. The integrated load detection feature is critical for monitoring unpredictable powerline impedance variations. Ensure the application design accommodates the specified junction temperature limits and utilizes external transient voltage protection to safeguard against mains surges and switching transients.

Part Context

This component belongs to the ACPL series of high-performance analog interface devices produced by Broadcom Limited. It is specifically engineered for robust signal transmission in electrically noisy environments typical of powerline networking. The device replaces older discrete amplifier solutions by integrating dual drivers, biasing circuits, and comprehensive protection mechanisms into a compact SO-8 package.

Replacement Considerations

Direct replacement requires verifying pin compatibility and electrical specifications such as supply voltage and drive current. Check datasheets for equivalent dual line drivers with similar gain bandwidth products and harmonic distortion characteristics. Confirm that any substitute component supports the same SO-8 package outline and meets the required operating temperature range.
