The MAX4080 / MAX4081 are high-side, current-sense Amplifiers with an input voltage range that extends from 4.5V to 76V making them ideal for telecom, automotive Backplane, and other systems where high-voltage current Monitoring is critical.
The MAX4080 is designed for unidirectional Current-sense applications and the MAX4081 Allows bidirectional current sensing.
The MAX4081 single Output pin continuously monitors the transition from Charge to discharge and avoids the need for a separate
Polarity output. The MAX4081 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 Apply 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, making the MAX4080 / MAX4081 Especially useful in a wide range of high-voltage systems The combination of three gain versions (5V / V, 20V / V 60V / V = F, T, S suffix) and a user-selectable, external Sense resistor sets the full-scale current reading and its
Proportional output voltage. The MAX4080 / MAX4081 Offer a high level of integration, resulting in a simple, accurate
And compact current-sense solution The MAX4080 / MAX4081 operate from a 4.5V to 76V single
Supply and draw only 75A of supply current Devices are specified over the automotive operating temperature Range (-40 ° C to + 125 ° C) and are available in a
