Digital
input
Enable Pin. When this pin is driven to VS, the device is on and functions as a
current sense amplifier. When this pin is driven to GND, the device is off, the
supply current is reduced, and the output is placed in a high-impedance state.
This pin must be driven externally, or connected to VS if not used. DDF package
only.

Analog
input
Current-sense amplifier negative input. For high-side applications, connect to
load side of sense resistor. For low-side applications, connect to ground side of
sense resistor.

Analog
input
Current-sense amplifier positive input. For high-side applications, connect to bus
voltage side of sense resistor. For low-side applications, connect to load side of
sense resistor.

Analog
output
OUT pin. This pin provides an analog voltage output that is the gained up
voltage difference from the IN+ to the IN– pins, and is offset by the voltage
applied to the REF pin.
REF

Analog
input
Reference input. Enables bidirectional current sensing with an externally applied
voltage. DCK and DDF packages only. Devices without a REF pin have this
node internally connected to GND.
