PBL3798-2 circuit equivalent, subscriber line interface circuit.
* On-chip switch mode regulator to minimize power dissipation
* Programmable, constant current feed
* Line feed characteristics independent of battery variati.
with -63 V < VBat < -56 V, the saturation guard reference voltage, VSGRef, should be adjusted by calculating a value for.
PBL 3798 is an analog Subscriber Line Interface Circuit (SLIC), which is fabricated in a 75 V bipolar, monolithic process. The programmable, constant current feed circuit incorporates a switch mode regulator to minimize on-chip power dissipation. A s.
