Part Details:

STLC3085 Integrated Pots interface for home access gateway and WLL Preliminary Data Features Monochip SLIC optimized for WLL & VoIP applications Implement all key features of Borsht function Single supply (4.5V to 12V) Built in DC/DC converter controller Soft battery reversal with programmable TQFP44 transition time On-hook transmission Programmable off-hook detector threshold Integrated ringing Integrated ring trip The battery level is properly adjusted depending Parallel control interface (3.3V logic level) on the operating mode. A useful characteristic forthese applications is the integrated ringing Programmable constant current feed generator. Surface mount package The control interface is parallel with open drain Integrated thermal protection output and 3.3V logic levels. Constant current Dual gain value option feed can be set from 20mA to 25mA. Automatic recognition flyback and buckboost Off-hook detection threshold is programmable configuration from 5mA to 9mA. BCDIIIS 90V technology The device, which is developed in BCDIIIS -40°C to +85°C operating range technology (90V process), operates in the extended temperature range and integrates a Description thermal protection that sets the device in power down when Tj exceeds 140°C. The STLC3085 is a SLIC device specificallydesigned for WLL (Wireless Local Loop), andISDN Terminal Adaptors and VoIP applications.One distinctive characteristic of this device is itsability to operate with a single supply voltage(from +4.5V to +12V) and to self generate thenegative battery by means of an on-chip DC/DCconverter controller that drives an external MOSswitch.
