MAX4373/MAX4374/MAX4375

General Description

Comparator + Reference ICs

Benefits and 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.

• Integrated Current-Sensing Solution Simplifies High-

Side Current Monitoring

• Current-Sense Amplifier plus Internal Comparator

and Bandgap Reference with Improved Accuracy

• 1mV (max) Input Offset Voltage

• 2% (max) Full-Scale Accuracy

• Internal Bandgap Reference ( 1ꢀ.% Accuracy)

• High Accuracy +2V to +28V Common-Mode Range,

Functional Down to 0V, Independent of Supply

Voltage Ensures Current Monitoring Even In Deep

Discharge of Battery Pack

• Low Power Consumption Extends Battery Life

• 50µA Supply Current

• Single +2ꢀ7V to +28V Operating Supply

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.

• Latching Comparator Output Eliminates Oscillation

• Three Gain Versions (+20V/V, +50V/V,

+100V/V) Support Different Size Battery Packs
