19-1434; Rev 1; 5/99 Low-Cost, SOT23, Voltage-Output, High-Side Current-Sense Amplifier General Description Features The MAX4173 low-cost, precision, high-side current- ¦ Low-Cost, Compact Current-Sense Solution sense amplifier is available in a tiny SOT23-6 package. ¦ Wide 0 to +28V Common-Mode Range It features a voltage output that eliminates the need for Independent of Supply Voltage gain-setting resistors and it is ideal for today’s notebook computers, cell phones, and other systems where cur- ¦ Three Gain Versions Available rent monitoring is critical. High-side current monitoring +20V/V (MAX4173T) is especially useful in battery-powered systems, since it +50V/V (MAX4173F) does not interfere with the ground path of the battery +100V/V (MAX4173H) charger.
