Low-Cost, Micropower, High-Side Current-Sense  
Amplifier + Comparator + Reference ICs  
General Description  
Features  
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.  
ꢀ Current-Sense Amplifier plus Internal Comparator  
and Bandgap Reference  
ꢀ 50µA Supply Current  
ꢀ Single +2.7V to +28V Operating Supply  
ꢀ 0.66% Full-Scale Accuracy

ꢀ Three Gain Versions Available (+20V/V, +50V/V,  
+100V/V)  
ꢀ Wide 0 to +28V Common-Mode Range,  
Independent of Supply Voltage  
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 50µA. They are  
specified for the extended operating temperature range  
(-40°C to +85°C) and are available in 8-pin and 10-pin  
µMAX packages.
