BLOCK DIAGRAM
OUT: Current Output. OUT will source a current that is
proportional to the sense voltage into an external resistor.
V–:
Negative Supply (or Ground for Single-Supply
Operation).
–IN: 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 the external RSENSE (Figure 1).
+IN: Must be tied to the system load end of the sense
resistor, either directly or through a resistor.
V+:
Positive Supply Pin. Supply current is drawn through
this pin. The circuit may be congured so that the
LTC6101 supply current is or is not monitored along
with the system load current. To monitor only system
load current, connect V+ to the more positive side of the
sense resistor. To monitor the total current, including the
LTC6101 current, connect V+ to the more negative side
of the sense resistor.
The LTC6101 high side current sense amplier (Figure 1)
provides accurate monitoring of current through a user-
selected sense resistor. The sense voltage is amplied by
a user-selected gain and level shifted from the positive
power supply to a ground-referred output. The output
signal is analog and may be used as is or processed with
an output lter.
Theory of Operation
An internal sense amplier loop forces IN– to have the
same potential as IN+. Connecting an external resis-
tor, RIN, between IN– and V+ forces a potential across
RIN that is the same as the sense voltage across
RSENSE. A corresponding current, VSENSE/RIN, will
ow through RIN. The high impedance inputs of the
sense amplier will not conduct this input current,
so it will ow through an internal MOSFET to the output pin.
The output current can be transformed into a voltage by
adding a resistor from OUT to V–. The output voltage is
then VO = V– + IOUT ROUT.
