MAX4080/MAX4081
76V, High-Side, Current-Sense Amplifiers
with Voltage Output
General Description
The MAX4080/MAX4081 are high-side, current-sense
amplifiers with an input voltage range that extends from
4.5V to 76V making them ideal for telecom, automotive,
backplane, and other systems where high-voltage current
monitoring is critical. The MAX4080 is designed for uni-
directional current-sense applications and the MAX4081
allows bidirectional current sensing. The MAX4081 sin-
gle output pin continuously monitors the transition from
charge to discharge and avoids the need for a separate
polarity output. The MAX4081 requires an external refer-
ence to set the zero-current output level (V
SENSE
= 0V).
The charging current is represented by an output voltage
from V
REF
to V
CC
, while discharge current is given from
V
REF
to GND.
For maximum versatility, the 76V input voltage range
applies independently to both supply voltage (V
CC
) and
common-mode input voltage (V
RS+
). High-side current
monitoring does not interfere with the ground path of the
load being measured, making the MAX4080/MAX4081
particularly useful in a wide range of high-voltage sys-
tems.
The combination of three gain versions (5V/V, 20V/V,
60V/V = F, T, S suffix) and a user-selectable, external
sense resistor sets the full-scale current reading and its
proportional output voltage. The MAX4080/MAX4081
offer a high level of integration, resulting in a simple, accu-
rate, and compact current-sense solution.
The MAX4080/MAX4081 operate from a 4.5V to 76V sin-
gle supply and draw only 75µA of supply current. These
devices are specified over the automotive operating tem-
perature range (-40°C to +125°C) and are available in a
space-saving 8-pin µMAX® or SO package.
