PIN FUNCTIONS
OUT (Pin 1): Current Output. OUT will source a current
that is proportional to the sense voltage into an external
resistor.
V(Pin 2): Normally Connected to Ground.
–IN (Pin 3): The internal sense amplier will drive –IN to
the same potential as +IN. A resistor (RIN) tied from V+ to
–IN sets the output current IOUT = VSENSE/RIN. VSENSE is
the voltage developed across RSENSE.
+IN (Pin 4): Must be tied to the system load end of the
sense resistor, either directly or through a resistor.
V+ (Pin 5): Positive Supply Pin. The V+ pin should be con-
nected directly to either side of the sense resistor, RSENSE.
Supply current is drawn through this pin. The circuit may
be congured so that the LT6107 supply current is or is
not monitored along with the system load current. To
monitor only the system load current, connect V+ to the
more positive side of the sense resistor. To monitor the
total current, including that of the LT6107, connect V+ to
the more negative side of the sense resistor.
