Unidirectionnal / bidirectionnal operation

•

Unidirectional operation

Unidirectional mode of operation allows the device to measure the current through a shunt resistor in one

direction only. The output reference can be ground or Vcc and can be set by using Vref1 and Vref2 pins for

adjustment.

•

Ground referenced

Figure 58. Output reference to ground

In this configuration Vref1 pin and Vref2 pin are connected together to the ground. The output common mode

voltage is then automatically set to GND when no current flows through the Rshunt resistance. This configuration

allows the full scale output in unidirectional mode. It allows a current to be measured as described in

Figure 58. Output reference to ground.

Vcc referenced
