SLIC-P - PEB4266 Subscriber Line Interface Circuit Enhanced Power Management

The High Voltage Subscriber Line Interface Circuit SLIC-P - PEB4266 is a reliable Interface between the telephone line and the codec devices of the DuSLIC or VINETIC chip sets. It is fabricated using Infineon Technologies well-proven Smart Power Technology SPT 170. Due to the integrated triple battery Switch the PEB4266 enables highly flexible solutions, e.g. 2 battery voltages (VBATH, VBATL) for power saving DC line feed and the third one (VBATR) for internal ring signal generation. With VBATR = 150 V, the amplitude of a balanced ringing signal may reach 85 Vrms. Besides, unbalanced ringing up to 50 Vrms CAN be chosen on either TIP (ROT) or RING (ROR). When using an external ring generator, the three battery voltages allow further reduction of power dissipation due to a still better adaptation of battery voltage to loop length. The PEB4266 is designed for a voltage-feeding/current-sensing line Interface concept and senses the transversal and longitudinal line current. To minimize system power dissipation, a power-down mode CAN be used; the PEB4266 is switched off and the line outputs go to a high-impedance mode. Off-hook supervision is provided by activating a simple line Current Sensor with negligible power consumption. The PEB4266 is compatible with both 3.3 V and 5 V VDD supplies.
