DESCRIPTION
The STLC30R80 is a SLIC device suitable for
short loop applications. The SLIC provides the
generation of the ringing signal and 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 cur-
rent region.
