I. Device Description
A. General
The MAX4172 is a low-cost, precision, high-side current-sense amplifier for portable PCs, telephones, and
other systems where battery/DC power-line monitoring is critical. High-side power-line monitoring is
especially useful in battery-powered systems, since it does not interfere with the battery charger’s ground
path. Wide bandwidth and ground-sensing capability make the MAX4172 suitable for closed-loop battery-
charger and general-purpose current-source applications. The 0V and 32V input common-mode range is
independent of the supply voltage, which ensures that current-sense feedback remains viable, even when
connected to a battery in deep discharge.
To provide a high level of flexibility, the MAX4172 functions with an external sense resistor to set the range of
load current to be monitored. It has a current output that can be converted to a ground-referred voltage with a
single resistor, accommodating a wide range of battery voltages and currents.
An open-collector power-good output (/PG) indicates when the supply voltage reaches an adequate level to
guarantee proper operation of the current-sense amplifier. The MAX4172 operates with a 3.0V to 32V supply
voltage.
