... The MAX4210D/E/F use an external resistor-divider network for greater design flexibility. The MAX4211 is a full-featured current and power mon- itor. The device combines a high-side current-sense amplifier, 1.21V bandgap reference, and two compara- tors with open-drain outputs to make detector circuits for overpower, overcurrent, and/or overvoltage condi- tions ...

... The common-mode voltage range is +4V to +28V and independent of the supply voltage. With this feature, the device can monitor the output current of a high-voltage source while running at a lower system voltage typically between 2.7V and 5.5V. The MAX4211 has a current-sense amplifier output. The voltage at IOUT is proportional to the voltage across V : SENSE ...
