CS-4173 1A high side current sensor module


    The CS-4173 is a Low-Cost, Compact Current-Sense module. It is detected by collecting the high-side current to achieve the load current, the main chip is MAX4173 high-side current-sense amplifier. The MAX4173 high-side current-sense amplifier features a 0 to +28V input common-mode range that is independent of supply voltage. This feature allows the monitoring of current out of a battery in deep discharge and also enables high-side current sensing at voltages greater than the supply voltage (VCC). High-side current monitoring is especially useful in battery-powered systems, since it does not interfere with the ground path of the battery charger. For the module, Derivation of calculation function is: Vout = Vsense * 50, I = Vsense/Rsense, so the end result is I = Vout/(50*Rsense) = Vout/5, the unit is A.
