MAX4376/MAX4377/  
MAX4378  
Single/Dual/Quad, High-Side Current-Sense  
Amplifiers with Internal Gain  
General Description  
Features  
o Low-Cost, Single/Dual/Quad, High-Side Current-  
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:  
Sense Amplifiers  
o ±±.ꢀ5 Typical Full-Scale Accuracy  
o +3V to +28V Supply Operation  
o Adjustable Current-Sense Capability with External  
Sense Resistor  
o Buffered Output Voltage with 2mA Drive  
o 1mA (typ) Supply Current  
o 2.±MHz Bandwidth (Gain = +2±V/V)  
o Automotive Temperature Range (-4±°C to +12ꢀ°C)  
o High Accuracy +2V to +28V Common-Mode  
Range, Functional Down to ±V, Independent of  
Supply Voltage

For example, MAX4376TAUK is a single high-side  
amplifier with a gain of 20.  
o Three Gain Versions Available  
+2±V/V (MAX437_T)  
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.  
+ꢀ±V/V (MAX437_F)  
+1±±V/V (MAX437_H)  
o Available in Space-Saving ꢀ-Pin SOT23 (Single),  
8-Pin µMAX (Dual), and 14-Pin TSSOP (Quad)  
Ordering Information  
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.
