Dual Channel miSLIC™ Series 150V Tracking Battery Device
Overview
We are transitioning to Microchip; this page will be directed to Le9672 product page at www.microchip.com.The miSLIC™ Series Subscriber Line Interface Circuit together with a VoIP processor or SoC, provides an economical turn-key solution for derived voice applications. The miSLIC device is controlled by a VoIP processor or SoC through a simple, single serial interface.
The Le9672 Tracking Battery miSLIC device provides high efficiency, 140 VPK high voltage ringing and system power management functions for two telephone line FXS ports. The dual channel Le9672 features wideband clarity and complete BORSCHT functionality.
Manufacturing test and subscriber line testing are standard features. All AC, DC, and power parameters are programmable making the miSLIC device suitable for any application requiring SLIC functionality.
