The MAX4069–MAX4072 low-cost, bidirectional, high-

side, current-sense amplifiers are ideal for monitoring

battery charge and discharge currents in notebooks,

cell phones, and other portable equipment. They fea-

ture up to 24V input common-mode voltage range, low

100µA supply current (which drops to only 10µA in

shutdown), and a total output error of less than 1.5%.

The wide 1.35V to 24V input common-mode range is

independent of the supply voltage, ensuring that the

current-sense feedback remains accurate even when

connected to a battery pack in deep discharge.

To achieve maximum flexibility, an external current-sense

resistor is used along with a Gain Select pin to choose

either 50V/V or 100V/V. A single output pin continuously

monitors the transition from charge to discharge and

avoids the need for a separate polarity output. The

MAX4070 contains an internal 2.5V reference. The

charging current is represented by an output voltage

from 2.5V to V

2.5V to GND. The MAX4071 is similar, but with a refer-

ence voltage of 1.5V. The MAX4069 has an adjustable

reference voltage, set by two external resistors. The

MAX4072 has an input for an external reference.

The MAX4069/MAX4071/MAX4072 operate from a 2.7V to

24V single supply. The MAX4070 operates from a 3.6V to

24V single supply. All devices are specified over the

automotive operating temperature range, -40°C to

+125°C. The MAX4070/MAX4071/MAX4072 are available

in 8-pin µMAX and 8-pin thin QFN packages. The

MAX4069 is available in a 10-pin µMAX

19-2423; Rev 3; 11/08
