BLOCK DIAGRAM
PIN FUNCTIONS
OUTA (Pin 1): Current Output of Amplier A. OUTA will
source a current that is proportional to the sense voltage
of amplier A into an external resistor.
OUTB (Pin 2): Current Output of Amplier B. OUTB will
source a current that is proportional to the sense voltage
of amplier B into an external resistor.
NC (Pin 3): No Connect.
V(Pin 4): Negative Supply (or Ground for Single Supply
Operation). Common to both ampliers.
+INB/VSB (Pin 5): The Positive Input of the Internal Sense
Amplier B. Must be tied to the system load end of the
sense resistor. It also works as the positive supply for
amplier B. Supply current of amplier B is drawn through
this pin. The LTC6103 supply current is monitored along
with the system load current.
–INB (Pin 6): The Negative Input of the Internal Sense
Amplier B. The internal sense amplier will drive –INB
to the same potential as +INB. A resistor (RIN) tied from
VB
+ to –INB sets the output current IOUT = VSENSE/ RIN.
VSENSE is the voltage developed across the external RSENSE
(Figure 1).
–INA (Pin 7): The Negative Input of the Internal Sense
Amplier A. The internal sense amplier will drive –INA
to the same potential as +INA. A resistor (RIN) tied from
VA
+ to –INA sets the output current IOUT = VSENSE/ RIN.
VSENSE is the voltage developed across the external RSENSE
(Figure 1).
+INA/VSA (Pin 8): The Positive Input of the Internal Sense
Amplier A. Must be tied to the system load end of the
sense resistor. It also works as the positive supply for
amplier A. Supply current of amplier A is drawn through
this pin. The LTC6103 supply current is monitored along
with the system load current.
