... As far as the DC characteristic is concerned three different feeding conditions are present: a) Current limiting region: the DC impedance of the SLIC is very high ( 20Kohm) and therefore the system works like a current source. Using the L3037 digital interface it is possible to select the value of the limiting current: 25mA, 44mA, or 55mA ...

... When the TTX function is not used TTXIN input should be connected to GND. Since this pin is di- rectly connected to a summing node inside the SLIC any signal applied to the TTXIN is transfer- red to the line with a fixed transfer gain. In special applications, this pin can be used to ...

... The power dissipation is very low. This mode is usually selected in emergency con- dition or when the connected line is disabled. This is also the mode into which the SLIC is auto- matically forced, in the case of thermal overload T > 150 C typ. ...
