Figure 7. The LT6105 Can Monitor the Current of Either Positive
or Negative Supplies, Without a Schematic Change. Just Ensure
That the Current Flow Is in the Correct Direction
Supply Monitoring
The input common mode range of the LT6105 also makes
it suitable for monitoring either positive or negative sup-
plies. Figure 7 shows one LT6105 applied as a simple
positive supply monitor, and another LT6105 as a simple
negative supply monitor. Note that the schematics are
practically identical and both have outputs conveniently
referred to ground. The only requirement for negative
supply monitoring, in addition to the usual constraints of
the absolute maximum ratings, is that the negative supply
to that LT6105 be at least as negative as the supply it is
monitoring.
