Description
The STLC3055N is a SLIC device specifically designed for wireless local loop (WLL) and ISDN terminal adaptors (ISDN-TA) and VoIP applications. One of the distinctive characteristic of this device is the ability to operate with a single supply voltage (from 5.5 V to 12 V) and 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 a parallel type with open drain output and 3.3 V logic levels.
