pin FuncTions
(TSOT-23/DFN)
NC (Pin 1/Pin 8): Not Internally Connected.
IOUT (Pin 2/Pin 7): Sinking Current Output. IOUT will sink
a current that is equal to V
SENSE
/R
IN.
V
SENSE
is the voltage
developed across the sense resisor.
IMON (Pin 3/Pin 6): Sourcing Current Output. IMON will
source a current that is equal to 3 • V
SENSE
/R
IN
.
V
–
(Pin 4/Pin 5): Negative Power Supply. Normally con-
nected to ground.
–IN
(Pin 5/Pin 4): Negative Input to the Internal Sense
Amplifier. Must be tied to system load side of the sense
resistor, either directly or through a resistor.
RS (Pin 6/Pin 3): Internal Sense Resistor. Connect to the
load to use. Leave open when using an external sense
resistor.
V
+
(Pin 7/Pin 2): Positive Power Supply. Connect to the
more positive side of the sense resistor. A minimum ca-
pacitance of 0.1µF is required from V
+
to V
–
.
+IN (Pin 8/Pin 1): Positive Input to the Internal Sense
Amplifier. The internal sense amplifier will drive +IN to the
same potential as –IN. A resistor, R
+IN
, tied from V
+
to +IN
sets the IOUT and IMON output currents as defined in the
the IOUT and IMON pin functions description.
Exposed Pad (Pin 9,
DFN Only): V
–
. Must be soldered
to the PCB.
