LTC6115
PIN FUNCTIONS –IN (Pin 1):
Inverting Input of the Current Sense Amplifier.
+IN (Pin 12):
Noninverting Input of the Current Sense The internal current sense amplifier will drive –IN to the Amplifier. Must be tied to the system load end of the sense same potential as +IN. resistor, either directly or through a resistor.
OUTI (Pin 3):
Current Output of Current Sense Amplifier.
V+ (Pin 11):
Positive Supply Pin for Current Sense Circuit. OUTI will source a current that is proportional to the sense Supply current for the current sense circuit is drawn voltage into an external resistor. through this pin.
GND (Pin 4):
Ground.
VIN (Pin 9):
Voltage Sense Amplifier Input Voltage.
FB(Pin 5):
