... Maximum Rating condition for extended periods may affect device reliability and lifetime. In addition to the Absolute Maximum Ratings, the output current of the LT6106 must be limited to insure that the power dissipation in the LT6106 does not allow the die temperature to exceed 150°C. See the applications information section “Power Dissipation Considerations” ...

... APPLICATIONS INFORMATION Introduction The LT6106 high side current sense amplifi er (Figure 1) pro- vides accurate monitoring of current through a user-selected sense resistor. The sense voltage is amplifi user- selected gain and level shifted from the positive power sup- ply to a ground-referred output. The output signal is analog and may be used as is, or processed with an output fi ...

... This amount of power dis- sipation will result in a 10°C rise in junction temperature above the ambient temperature important to note that the LT6106 has been designed to provide at least 1mA to the output when required, and can deliver more depending on the conditions. Care must be taken to limit the maximum output current by proper – ...

... APPLICATIONS INFORMATION In addition, if the output of the LT6106 is wired to a de- vice that will effectively short it to high voltage (such as through an ESD protection clamp) during a reverse sup- ply condition, the LT6106’s output should be connected through a resistor or Schottky diode (Figure 7). Demo Board Demo board DC1240 is available for evaluation of the LT6106 ...
