MAX4006

High-Accuracy, High-Side Current Monitors in SOT23

Precision, High-Side 10:1 Current Monitor Senses Currents from 10nA to 10mA


Please check latest availability status for a specific part variant.

Description

The MAX4004/MAX4006 precision, high-side, current monitors are specifically designed for monitoring photodiode 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 proportional to the reference current. The monitor output of the MAX4006 is a voltage proportional to the reference current. 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 supply 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.
