DESCRIPTION

The STLC30R81 is a low voltage SLIC suitable for

short loop applications. All the BORSHT and test

functions (phone detection, loop-back, short circuit

detection) are integrated in this device. It provides

three ringing modes: Sinusoidal, Trapezoidal and

PWM waveform.

In sinusoidal ringing modes, depending on the CO-

DEC’s functionalities and characteristics Rxin+/Rxin-

or Rg+/Rg- paths can be selected. When CODEC

can manage low frequency signals Rxin+/ Rxin- will

be used.

This device can also limit the peak current during On-

Hook/Off-Hook transition and Ring-trip detection.

The device is based on BCD3S 90V technology and

it can work at 3.3V power supply.

The TQFP44 Package with SLUG increases the

SLIC performance in terms of power dissipation mak-

ing unnecessary the use of any external power com-

ponents.
