MAX4004/MAX4006

High-Accuracy, High-Side Current Monitors

in SOT23

General Description

The MAX4004/MAX4006 precision, high-side, current

monitors are specifically designed for monitoring photo-

diode current in fiber applications. They offer a connection

point for the reference current and a monitor output that

produces a signal proportional to the reference current.

The monitor output of the MAX4004 is a current propor-

tional to the reference current. The monitor output of the

MAX4006 is a voltage proportional to the reference cur-

rent. The current monitors have six decades of dynamic

range and monitor reference current of 250nA to 2.5mA

with better than 5% accuracy. The photodiode current can

be monitored from 10nA to 10mA with reduced accuracy.

The MAX4004/MAX4006 accept a +2.7V to +22V sup-

ply voltage, suitable for PIN photodiode applications.

(For higher voltage applications, refer to the MAX4007/

MAX4008 data sheet.) Internal current limiting (20mA,

typ) protects the device against short-circuit-to-ground

or excessive current conditions. A clamp diode protects

the monitor output from overvoltage. Additionally, these

devices feature thermal shutdown if the die temperature

reaches +150°C.

The MAX4004/MAX4006 are available in tiny, space-

saving 6-pin SOT23 packages, and operate over the

extended temperature range of -40°C to +85°C.
