Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Output voltage of the current-sense amplifier, bounded by the supply (swings from 80mV to 100mV below VS) and referenced to the REF pin voltage. |
| 2 | GND | power_in | Ground. |
| 3 | IN+ | input | Current-sense amplifier positive input; for high-side use connect to the bus-voltage side of the sense resistor, for low-side use connect to the load side, with common-mode range -2V to 42V. |
| 4 | IN- | input | Current-sense amplifier negative input; for high-side use connect to the load side of the sense resistor, for low-side use connect to the ground side, with common-mode range -2V to 42V. |
| 5 | REF | input | Reference voltage input; connect to a voltage potential from 0V to VS to set the output at zero differential input. |
| 6 | VS | power_in | Power supply, 2.7V to 12V. |
