Ground connection
Output current pin. Current generated due to a difference voltage
between V
value resistor connected to ground creates an output voltage. The
maximum voltage out of this pin will be V
measured and also provides power to internal circuitry. It is the
positive input of the current monitor and has an input range from
20V down to 2.5V. The current through this pin varies with
differential sense voltage.
