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 3.3V logic levels. Constant current feed can be set from 20m A to 25m A. Off-hook detection threshold is programmable from 5m A to 9m A. 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..
