Integrated Pots Interface

for Home Access Gateway and WLL

Preliminary Data

Features

■ Monochip SLIC optimised for WLL & VoIP

applications

■ Implement all key features of the borsht

function

■ Single supply (4.5 to 12V)

■ Built in DC/DC Converter controller

TQFP44

■ Soft battery reversal with programmable

transition time

■ On-hook transmission

■ Programmable off-hook detector threshold

■ Integrated ringing

is the ability to operate with a single supply

voltage (from +4.5V to +12V) and self generate

the negative battery by means of an on chip DC/

DC converter controller that drives an external

MOS switch.

■ Integrated ring trip

■ Parallel control interface (3.3V logic level)

■ Programmable constant current feed

■ Surface mount package

The battery level is properly adjusted depending

on the operating mode. A useful characteristic for

these applications is the integrated ringing

generator.

■ Integrated thermal protection

■ Dual gain value option

■ Automatic recognition flyback and buckboost

The control interface is a parallel type with open

drain output and 3.3V logic levels. Constant

current feed can be set from 20mA to 25mA.

configuration

■ BCDIIIS 90V technology

■ -40 to +85°C operating range

Off-hook detection threshold is programmable

from 5mA to 9mA.

Description

The device, developed in BCDIIIS technology

(90V process), operates in the extended

temperature range and integrates a thermal

protection that sets the device in power down

when Tj exceeds 140°C..

The STLC3085 is a SLIC device specifically

designed for WLL (Wireless Local Loop), and

ISDN Terminal Adaptors and VoIP applications.
