DESCRIPTION

The STLC3080 is a SLIC device suitable for a wide range of applications: public (CO), transmission (DLC) and private (PABX). The SLIC provides the standard battery feeding with full programmability of the DC characteristic. In particular two external resistors allow to set the limiting current value (up to 50mA) and the value of the resistive feeding when not in constant current region.
