Pin Name

Description

REF

Reference input. Enable bidirectional current sensing with an externally applied voltage

GND

Ground

VS

Power supply

EN

Enable Pin

IN+

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

IN-

Negative input

For high-side applications, connect to load side of sense resistor

For low-side applications, connect to ground side of sense resistor

OUT

Output voltage. Provide 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
