FEATURES

LT6100

Precision, Gain Selectable

High Side Current Sense

Amplifier

DESCRIPTION

The

6100

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.

The LT6100 sense inputs have a voltage range that extends

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 300µV. 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 60µA. When V

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.
