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 current region.
