Single/Dual/Quad, High-Side Current-Sense

Amplifiers with Internal Gain

General Description

Features

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:

ꢀ Low-Cost, Single/Dual/Quad, High-Side Current-

Sense Amplifiers

ꢀ Buffered Output Voltage with 2mA Drive

ꢀ 1mA (tꢀp) Supplꢀ Current

ꢀ 20±MHz Bandwidth (Gain = +2±V/V)

ꢀ Automotive Temperature Range (-4±°C to +12.°C)

For example, MAX4376TAUK is a single high-side

amplifier with a gain of 20.

ꢀ 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)

ꢀ Available in Spaꢁe-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.

MAX4376FAUK-T

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.
