General Description
The MAX4373/MAX4374/MAX4375 low-cost, micropow-
er, high-side current-sense supervisors contain a high-
side current-sense amplifier, bandgap reference, and
comparator with latching output. They feature a voltage
output that eliminates the need for gain-setting resistors,
making them ideal for today’s notebook computers, cell
phones, and other systems where battery/DC current
monitoring is critical. High-side current monitoring is
especially useful in battery-powered systems since it
does not interfere with the ground path of the battery
charger. The 0 to +28V input common-mode range is
independent of the supply voltage, which ensures that
the current-sense feedback remains viable even when
connected to a battery pack in deep discharge.
The comparator output of the MAX4373/MAX4374/
MAX4375 is latched to provide a turn-off flag that
doesn’t oscillate. In addition, the MAX4374/MAX4375
contain a second comparator for use in window-detec-
tion functions. The MAX4373/MAX4374/MAX4375 are
available in three different gain versions (T = +20V/V,
F = +50V/V, H = +100V/V) and use an external sense
resistor to set the sensitivity of the input voltage to the
load current. These features offer a high level of inte-
gration, resulting in a simple and compact current-
sense solution.
The MAX4373/MAX4374/MAX4375 operate from a sin-
gle +2.7V to +28V supply and consume 50A. They are
specified for the extended operating temperature range
(-40°C to +85°C) and are available in 8-pin and 10-pin
MAX packages.
