LTC6102 LTC6102-1/LTC6102HV
pin FuncTions –INS (Pin 1):
Amplifier Inverting Input. When tied to –INF,
V– (Pin 5):
Negative Supply. the internal sense amplifier will drive –INS to the same
V
potential as +IN.
REG (Pin 6):
Internal Regulated Supply. A 0.1µF (or larger) capacitor should be tied from VREG to V+. VREG is
–INF (Pin 2):
Force Input. This pin carries the input not designed to drive external circuits. current from RIN and must be tied to –INS near RIN. A
V+ (Pin 7):
Positive Supply. Supply current is drawn resistor (RIN) tied from V+ to –INF sets the output current through this pin. IOUT = VSENSE/RIN. VSENSE is the voltage across the ex- ternal RSENSE.
+IN (Pin 8):
Amplifier Noninverting Input. Must be tied to the system load end of the sense resistor. The +IN pin
V– (Pin 3, LTC6102/LTC6102HV Only):
Negative Supply. has an internal 5k series resistor designed to allow large
EN (Pin 3, LTC6102-1 Only):
Enable Pin, Referenced to input voltage transients or accidental disconnection of the the Negative Supply. When the enable pin is pulled high, sense resistor. This pin can be held up to 20V below the the LTC6102-1 is active. When the enable pin is pulled low –INS pin indefinitely, or up to 60V below the –INS pin for or left floating, the LTC6102-1 is disabled. up to one second (see Absolute Maximum Ratings).
OUT (Pin 4):
Open-Drain Current output. OUT will source
Exposed Pad (Pin 9, DFN Only):
V–. The Exposed Pad a current that is proportional to the sense voltage into must be soldered to PCB. an external resistor. IOUT is the same current that enters –INF. 6102fe 10 For more information www.linear.com/LTC6102
