LE9672WQC

Telecom Overview

The LE9672WQC is a two-channel Subscriber Line Interface Circuit (miSLIC) designed for telecom applications. It operates with a supply voltage range of 3.135V to 3.465V and draws a typical supply current of 25mA. The device supports a tracking voltage up to 150V and provides an isolation rating of 58dB. It utilizes a 56-pin VFQFN exposed pad package and functions within an operating temperature range of -40°C to +85°C.

Telecom Feature Summary

• Integrates two independent subscriber line interface channels in a single compact package.
• Supports high-voltage tracking capabilities up to 150V for robust line signaling.
• Features low power consumption suitable for dense telecommunications equipment.

Telecom Applications

• Digital loop carrier systems
• Subscriber line interface circuits
• Telecommunications network infrastructure

Telecom Procurement Notes

Verify the specific ordering suffix and packaging configuration, as the component may be supplied in trays or tape-and-reel formats depending on the exact part number variant. Confirm RoHS compliance status and ensure the selected package matches the PCB footprint requirements. Cross-reference the datasheet revision to confirm electrical characteristics align with the design specifications before finalizing procurement orders.

Telecom Selection Notes

Select this component for designs requiring dual-channel subscriber line interfacing with integrated high-voltage handling. Ensure the system power supply remains within the specified 3.135V to 3.465V range to maintain proper operation. Consider the thermal performance of the exposed pad VQFN package for adequate heat dissipation in enclosed environments.

Telecom Part Context

The LE9672WQC belongs to Microchip's miSLIC family of telecom interface ICs. These components are engineered to simplify the design of subscriber line interfaces by integrating necessary analog and digital functions into a single solution, reducing board space and complexity compared to discrete implementations.

Telecom Replacement Considerations

Consult official Microchip documentation for direct pin-to-pin compatible alternatives within the LE9xxx series. Verify that any substitute part maintains identical voltage ratings, channel count, and package dimensions to ensure seamless integration without redesigning the host circuit board.
