DESCRIPTION

The STLC3080 is a SLIC device suitable for a

wide range of applications: public (CO), transmis-

sion (DLC) and private (PABX). The SLIC pro-

vides the standard battery feeding with full pro-

grammability of the DC characteristic. In particular

two external resistors allow to set the limiting cur-

rent value (up to 50mA) and the value of the re-

sistive feeding when not in constant current re-

gion.
