General Description
The MAX4376/MAX4377/MAX4378 single, dual, and
quad precision high-side current-sense amplifiers are
available in space-saving packages. They feature
buffered voltage outputs that eliminate the need for
gain-setting resistors and are ideal for today’s notebook
computers, cell phones, and other systems where cur-
rent monitoring is critical. These precision devices are
offered in three fixed-gain versions of 20, 50, and 100:
GAIN
20
50
100
For example, MAX4376TAUK is a single high-side
amplifier with a gain of 20.
High-side current monitoring is especially useful in bat-
tery-powered systems since it does not interfere with
the ground path of the battery charger. The input com-
mon-mode range of 0 to +28V is independent of the
supply voltage and ensures that the current-sense
feedback remains viable even when connected to a
battery pack in deep discharge.
The full-scale current reading can be set by choosing
the appropriate voltage gain and external-sense resis-
tor. This capability offers a high level of integration and
flexibility, resulting in a simple and compact current-
sense solution.
The MAX4376/MAX4377/MAX4378 operate over a sup-
ply voltage range of +3V to +28V, draw 1mA of supply
current per amplifier, and operate over the full automo-
tive temperature range of -40
°
C to +125
°
C. These
devices have a wide bandwidth of 2MHz, making them
suitable for use inside battery-charger control loops.
The buffered outputs drive up to 2mA of output current
into a ground-referenced load.
The MAX4376 is available in a tiny 5-pin SOT23 pack-
age. The MAX4377/MAX4378 are available in space-
saving 8-pin μMAX and 14-pin TSSOP packages,
respectively.
