Part Details:

STLC3075 Integrated POTS interface for home access gateway and WLL Features Monochip SLIC optimized for WLL & VoIP applications Implements all Borsht function key features Single supply (4.5V to 12V) for fly-back TQFP44 configuration The battery level is properly adjusted depending Single supply (5.5V to 12V) for buck-boost on the operating mode. A useful characteristic for configuration these applications is the integrated ringing Built in DC/DC converter controller generator. Soft battery reversal with programmable The control interface is parallel with open drain transition time output and 3.3V logic levels. On-hook transmission The metering pulses are generated on-chip Programmable off-hook detector threshold starting from two logic signals (0, 3.3V): one Metering pulse generation and filter signal defining the metering pulse frequency, the other signal defining the metering pulse duration. Integrated ringing An on-chip circuit then provides the proper Integrated ring trip shaping and filtering. Metering pulse amplitude Parallel control interface (3.3V logic level) and shaping (rising and decay time) can be programmed by external components. Programmable constant current feed Surface mount package A dedicated cancellation circuit avoids possible CODEC input saturation due to metering pulse Integrated thermal protection echo. Dual gain value option Constant current feed can be set from 20mA to Automatic recognition flyback and buckboost 40mA. Off-hook detection threshold is configuration programmable 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 STLC3075 is a SLIC device specifically designed for WLL (Wireless Local Loop), and ISDN terminal adaptors and VoIP applications. One distinctive characteristic of this device is its ability to operate with a single supply voltage (from +4.5V to +12V) and to self generate the negative battery by means of an on-chip DC/DC converter controller that drives an external MOS switch.
