DESCRIPTION
High Temperature High Side
Current Sense Amp in SOT-23
The LT
®
6107 is a versatile high side current sense ampli-
fier designed for operation over a wide temperature range.
Design flexibility is provided by the excellent device char-
acteristics: 250µV maximum offset and 40nA maximum
input bias current. Gain for each device is set by two
resistors and allows for accuracy better than 1%.
The LT6107 monitors current via the voltage across an
external sense resistor (shunt resistor). Internal circuitry
converts input voltage to output current, allowing for a
small sense signal on a high common mode voltage to
be translated into a ground referenced signal. The low DC
offset allows for monitoring very small sense voltages. As
a result, a small valued shunt resistor can be used, which
minimizes the power loss in the shunt.
The wide 2.7V to 44V input voltage range, high accuracy
and wide operating temperature range make the LT6107
ideal for automotive, industrial and power management
applications. The very low power supply current of the
LT6107 also makes it suitable for low power and battery
operated applications. For applications not requiring the
wide temperature range, see the LT6106.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime. In addition to the Absolute Maximum Ratings, the
output current of the LT6107 must be limited to insure that the power
dissipation in the LT6107 does not allow the die temperature to exceed
150°C. See the applications information section “Power Dissipation
Considerations” for further information.
Note 2: Junction temperatures greater than 125°C will promote
accelerated aging. The LT6107 has demonstrated typical life beyond 1000
hours at 150°C. LT6107H is guaranteed to meet specified performance
from –40°C to 150°C. LT6107MP is guaranteed to meet specified
performance from –55°C to 150°C.

Note 3: Guaranteed by the gain error test.
Note 4: Gain error refers to the contribution of the LT6107 internal circuitry
and does not include errors in the external gain setting resistors.
Note 5: The LT6107 output is an open collector current source. The
minimum output voltage scales directly with the ratio R
OUT
/10k.
Note 6: V
SENSE
+
is the voltage at the high side of the sense resistor,
R
SENSE
. See Figure 1.
Note 7: V
SENSE(MAX)
is the maximum sense voltage for which the Electrical
Characteristics will apply. Higher voltages can affect performance but will
not damage the part provided that the output current of the LT6107 does
not exceed the allowable power dissipation as described in Note 1.
