DescripTion
Precision, Gain Selectable
High Side Current Sense
Amplifier
The LT6100 is a complete micropower, precision, high
side current sense amplifier. The LT6100 monitors unidi-
rectional currents via the voltage across an external sense
resistor. Fixed gains of 10, 12.5, 20, 25, 40, 50V/V are
obtained by simply strapping or floating two gain select
pins. Gain accuracy is better than 0.5% for all gains.
TheLT6100senseinputshaveavoltagerangethatextends
from 4.1V to 48V, and can withstand a differential voltage
of the full supply. This makes it possible to monitor the
voltage across a MOSFET switch or a fuse. The part can
also withstand a reverse battery condition on the inputs.
Input offset is a low 300V. CMRR and PSRR are in ex-
cess of 105dB, resulting in a wide dynamic range. A filter
pin is provided to easily implement signal filtering with a
single capacitor.
The LT6100 has a separate supply input, which operates
from 2.7V to 36V and draws only 60A. When VCC is
powered down, the sense pins are biased off. This pre-
vents loading of the monitored circuit, irrespective of the
sense voltage. The LT6100 is available in an 8-lead DFN
and MSOP package.
