MAX4081TAUA+ - Maxim Integrated Function Overview

The MAX4081TAUA+ is a 76V, high side, current sense amplifier with voltage output in 8 pin µMAX package. The device allows bidirectional current sensing applications, single output pin continuously monitors the transition from charge to discharge and avoids the need for a separate polarity output. It requires an external reference to set the zero-current output level (VSENSE = 0V). The charging current is represented by an output voltage from VREF to VCC while discharge current is given from VREF to GND. For maximum versatility, the 76V input voltage range applies independently to both supply voltage (VCC) and common-mode input voltage (VRS+). High side current monitoring does not interfere with the ground path of the load being measured, this makes the device particularly useful in wide range of high voltage systems. Device offer a high level of integration resulting in a simple, accurate and compact current sense solution.
