LE9662

The miSLIC™ Line Circuits together with a VoIP processor or SoC, provide an economical turn-key solution for derived voice applications. The miSLIC devices are controlled by a VoIP processor or SoC through a simple, single serial interface. The dual channel Le9662 miSLIC device uses energy efficient shared power supply topologies for reduced BOM cost. The Le9662 can be configured for patent-pending shared Buck-Boost Automatic Battery Switching (BBABS) or for shared flyback ABS (FBABS) operation. Ringing and system power management are supported to limit the peak power requirements of each telephone line FXS port. The dual channel Le9662 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.
