LE9652PQCT

Telecom Overview

The LE9652PQCT is a dual-channel Subscriber Line Interface Circuit (SLIC) manufactured by Microchip Technology. It integrates two independent FXS line interfaces designed for telecommunication applications, supporting up to 120V absolute maximum line voltage. The device operates within a supply voltage range of 3.135 V to 3.465 V and consumes a typical operating current of 25 mA. It features a QFN-53 package suitable for surface mount technology and supports serial interface communication protocols. The component is rated for an operating temperature range from -40°C to +85°C and includes integrated power dissipation capabilities of 1.5 W.

Telecom Feature Summary

• Dual-channel architecture providing independent FXS line interface functionality
• Integrated high-voltage support for standard telephony line requirements
• Compact surface-mount packaging optimized for space-constrained designs

Telecom Applications

• Digital subscriber line access multiplexer (DSLAM) equipment
• Voice over IP (VoIP) gateway devices
• Central office telephony interface modules

Telecom Procurement Notes

Verify the specific ordering suffix PQCT against official Microchip documentation to confirm reel quantity and tape-and-reel specifications. Confirm availability status as distribution channels may list discontinued or limited stock items. Ensure compliance with RoHS directives if required for the target assembly process.

Telecom Selection Notes

Select this component when a dual-channel SLIC solution is required for FXS applications. Compare pin compatibility and thermal performance against single-channel alternatives like the LE9651 series. Verify that the QFN-53 footprint aligns with the printed circuit board layout constraints and manufacturing capabilities.

Telecom Part Context

This part belongs to the LE96xx family of Subscriber Line Interface Circuits from Microchip Technology. These components are engineered to replace legacy discrete solutions in modern telecommunication infrastructure, offering integrated protection and signaling functions within a single semiconductor package.

Telecom Replacement Considerations

Consult official Microchip substitution guides for direct replacements. Consider the LE9652RQCT variant if different reel quantities are required. Evaluate the LE9651PQCT for single-channel applications requiring similar electrical characteristics.
