LMP8602/LMP8602Q/

LMP8603/LMP8603Q

60V Common Mode, Fixed Gain, Bidirectional Precision

Current Sensing Amplifier

General Description

Features

The LMP8602 and LMP8603 are fixed gain precision ampli-

fiers. The parts will amplify and filter small differential signals

in the presence of high common mode voltages. The input

common mode voltage range is –22V to +60V when operating

from a single 5V supply. With a 3.3V supply, the input com-

mon mode voltage range is from –4V to +27V. The LMP8602

and LMP8603 are members of the Linear Monolithic Precision

(LMP^®) family and are ideal parts for unidirectional and bidi-

rectional current sensing applications. All parameter values

of the parts that are shown in the tables are 100% tested and

all bold values are also 100% tested over temperature.

Unless otherwise noted, typical values at T_A= 25°C,

V_S= 5.0V, Gain = 50x (LMP8602), Gain = 100x (LMP8603)

The parts have a precise gain of 50x for the LMP8602 and

100x for the LMP8603, which are adequate in most targeted

applications to drive an ADC to its full scale value. The fixed

gain is achieved in two separate stages, a preamplifier with a

gain of 10x and an output stage buffer amplifier with a gain of

5x for the LMP8602 and 10x for the LMP8603. The connection

between the two stages of the signal path is brought out on

two pins to enable the possibility to create an additional filter

network around the output buffer amplifier. These pins can

also be used for alternative configurations with different gain

as described in the applications section.

LMP8602Q and LMP8603Q available in Automotive AEC-

Q100 Grade 1 qualified version

Applications

High side and low side driver configuration current sensing

■

Bidirectional current measurement

Current loop to voltage conversion

Automotive fuel injection control

Transmission control

Power steering

The mid-rail offset adjustment pin enables the user to use

these devices for bidirectional single supply voltage current

sensing. The output signal is bidirectional and mid-rail refer-

enced when this pin is connected to the positive supply rail.

With the offset pin connected to ground, the output signal is

unidirectional and ground-referenced.

Battery management systems

The LMP8602 and LMP8603 are available in a 8–Pin SOIC

package and in a 8–Pin MSOP package.

The LMP8602Q and LMP8603Q incorporate enhanced man-

ufacturing and support processes for the automotive market,

including defect detection methodologies. Reliability qualifi-

cation is compliant with the requirements and temperature

grades defined in the AEC Q100 standard.
