Datasheet Specifications

Part number: PBL3796-2
Manufacturer: Ericsson
File Size: 365.37 KB
Datasheet: PBL3796-2-Ericsson.pdf
Description: Subscriber Line Interface Circuit

Features

* On-chip switch mode regulator to minimize power dissipation
* Programmable, resistive battery feed with short-loop current limiting
* Line feed characteristics independent of battery variations
* Tip-ring polarity reversal function
* Tip and ring open circui

Applications

* with -63V< VBat< -56V, the saturation guard reference voltage, VSGRef, should be adjusted by calculating a value for resistor RSG as described in the text. Not that the adjustment terminal, RSG, is available only on the 44-pin leaded chip carrier packages. 9. VBat should be applied with a ∂VBat/∂t
