The STLC3075 is a SLIC device specifically designed for WLL (Wireless Local Loop), ISDN terminal adaptors, and VoIP applications. One distinctive characteristic of this device is its ability to operate with a single supply voltage (from +4.5 V to +12 V) and to self-generate the negative battery by means of an on-chip DC/DC converter controller that drives an external MOS switch. The battery level is properly adjusted depending on the operating mode. A useful characteristic for these applications is the integrated ringing generator. The control interface is parallel with open-drain output and 3.3 V logic levels. The device also includes features such as a programmable off-hook detector threshold, metering pulse generation and filter, integrated thermal protection, and a dual gain value option.
The STLC3075 is a monolithic SLIC (Subscriber Line Interface Circuit) device optimized for Wireless Local Loop (WLL), ISDN terminal adaptors, and Voice over IP (VoIP) applications. It features an integrated DC/DC converter controller that allows operation with a single supply voltage ranging from 4.5 V to 12 V, enabling both fly-back and buck-boost configurations without external negative battery generation circuits.
The device implements all Borscht function key features, including soft battery reversal with programmable transition time, on-hook transmission, integrated ringing generation, and metering pulse generation. It operates in a temperature range of -40 °C to +85 °C using 90 V BCDIIIS technology and includes built-in thermal protection.
