Description
AI
The miSLIC™ Line Circuits together with a VoIP processor or SoC, provide an economical turn-key solution for derived voice applications. The dual channel Le9622 miSLIC device uses energy efficient shared power supply topologies for reduced BOM cost. The Le9622 can be configured for patented Triple Buck-Boost Automatic Battery Switching (TBABS) or Buck-Boost ABS (BBABS) operation or for multi-line inverting boost operation. Ringing and system power management are supported to limit the peak power requirements of each telephone line FXS port. The dual channel Le9622 features wide-band 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.
