THS6222IRHFR

Overview

The THS6222IRHFR is a differential broadband power line communication (PLC) and high-performance PLC (HPLC) line driver manufactured by Texas Instruments. It utilizes a current feedback architecture built on a proprietary silicon-germanium (SiGe) process to deliver high linearity for driving heavy line loads. The device operates within an 8 V to 32 V supply voltage range and features an integrated mid-supply common-mode buffer, eliminating the need for external components. It supports both inverting and non-inverting polarities across two input and two output lines.

Feature Summary

• Integrates a mid-supply common-mode buffer to reduce system component count and board space requirements
• Utilizes a current feedback architecture with high-speed SiGe technology for superior signal linearity
• Provides high output current capability suitable for driving demanding transmission line loads

Applications

• Broadband Power Line Communication (PLC) systems
• High-Performance Power Line Communication (HPLC) line drivers
• Smart metering infrastructure
• Data concentrator units

Procurement Notes

Verify the specific suffix IRHFR indicates the tape-and-reel packaging format and industrial temperature grade (-40°C to +85°C). Confirm that the order quantity aligns with standard reel sizes if bulk procurement is required. Ensure compatibility with moisture sensitivity levels during storage and handling procedures as specified in the official datasheet.

Selection Notes

Select this component when designing circuits requiring high linearity and significant output current for power line communication applications. The integrated common-mode buffer simplifies design complexity compared to discrete solutions. Consider the 8 V to 32 V operating range to ensure it matches the target power supply rails of the communication module.

Part Context

This part belongs to the THS6222 series of differential line drivers designed specifically for power line communication environments. It shares architectural similarities with other devices in the family but is optimized for broadband performance. The device is housed in a 24-pin VQFN package with an exposed thermal pad to facilitate heat dissipation during operation.

Replacement Considerations

The THS6222IRGTR is a pin-compatible alternative available in a different package configuration. Verify footprint dimensions and thermal requirements before substituting.
