PBL3796 circuit equivalent, subscriber line interface circuit.
* On-chip switch mode regulator to minimize power dissipation
* Programmable, resistive battery feed with short-loop current limiting
* Line feed characterist.
with -63V< VBat< -56V, the saturation guard reference voltage, VSGRef, should be adjusted by calculating a value for res.
PBL 3796 is an analog Subscriber Line Interface Circuits (SLICs), which are fabricated in a 75 V bipolar, monolithic process. The programmable battery feed is resistive with short-loop current limiting. A switch-mode regulator reduces on-chip power d.
