INA181A1IDBVT from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | output | Output voltage from the current sense amplifier. |
| 2 | GND | power_in | Analog ground reference. |
| 3 | IN+ | input | Current sense amplifier positive input; for high-side applications connect to the bus voltage side of the sense resistor, for low-side applications connect to the load side of the sense resistor. |
| 4 | IN- | input | Current sense amplifier negative input; for high-side applications connect to the load side of the sense resistor, for low-side applications connect to the ground side of the sense resistor. |
| 5 | REF | input | Reference input voltage, 0V to VS, used to bias the output for single or bidirectional current measurement. |
| 6 | VS | power_in | Power supply input, 2.7V to 5.5V, with 0.1µF bypass capacitor recommended. |
