INA181A2QDBVRQ1 from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Analog output voltage of the current-sense amplifier; the output swings between the rails and is limited to 0 to VS, with the output current maximum at 8 mA. |
| 2 | GND | power_in | Analog ground pin. |
| 3 | IN+ | input | Positive current-sense amplifier input; for high-side sensing connect to the bus-voltage side of the sense resistor, and for low-side sensing connect to the load side. Common-mode range is -0.2 V to 26 V. |
| 4 | IN- | input | Negative current-sense amplifier input; for high-side sensing connect to the load side of the sense resistor, and for low-side sensing connect to the ground side. Common-mode range is -0.2 V to 26 V. |
| 5 | REF | input | Reference input that sets the output level at zero differential input; it can be set anywhere from 0 V to VS and must not exceed VS. |
| 6 | VS | power_in | Analog power supply pin, 2.7 V to 5.5 V (absolute maximum 6 V). |
