ISL15102AIRZ

Overview

The ISL15102AIRZ is a single-port differential line driver designed for Power Line Communication (PLC) applications. It features a 90MHz signal bandwidth and a 900V/μs slew rate, supporting narrowband and broadband DMT PLC standards. The device operates on a single +8V to +28V supply with an absolute maximum of 30V. Key electrical parameters include a typical noise voltage of 8.5nV/√Hz, a maximum offset voltage of 17mV, and a thermal shutdown threshold at +150°C. It is housed in a thermally enhanced 4mm x 5mm 24-lead QFN package and specified for operation from -40°C to +105°C.

Feature Summary

• Single differential driver optimized for heavy line loads while maintaining high linearity required in OFDM PLC modem links.
• Built-in disable control pin allows entry into low-power mode with high-impedance outputs to improve TDM receive signal integrity.
• Internal input common-mode buffer maximizes dynamic range and reduces the number of external components required in the application circuit.

Applications

• Smart single-phase electricity meters
• Flexible power metering systems with wired communication capabilities
• Power line voice communication nodes

Procurement Notes

Verify the specific suffix 'AIRZ' against official Renesas documentation to confirm temperature grade and packaging details. Ensure compatibility with the ISL15102IRZ-EVALZ evaluation board if prototyping. Confirm RoHS compliance status and lead-free specifications prior to ordering.

Selection Notes

Select this component for PLC designs requiring high linearity and drive capability. Consider the internal VCM buffer for simplified schematic design. Evaluate the thermal performance given the +105°C upper operating limit and built-in thermal protection at +150°C.

Part Context

The ISL15102 belongs to Renesas' portfolio of analog interface solutions for smart grid infrastructure. It complements PLC modem ICs like the R9A06G037 by providing the necessary physical layer signal driving capability over power lines.
