INA241A5QDDFRQ1 from Texas Instruments, in a TSOT-23-8. 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 | IN- | input | Current-sense amplifier negative input connecting to either load side of sense resistor (high-side) or ground side of sense resistor (low-side). |
| 2 | GND | power_in | Ground. |
| 3 | REF2 | input | Reference 2 voltage input with potential range from 0 V to VS. |
| 4 | NC | unconnected | Reserved pin that must be connected to ground. |
| 5 | OUT | output | Output voltage. |
| 6 | VS | power_in | Power supply with operating range 2.7 V to 20 V. |
| 7 | REF1 | input | Reference 1 voltage input with potential range from 0 V to VS. |
| 8 | IN+ | input | Current-sense amplifier positive input connecting to either bus-voltage side of sense resistor (high-side) or load side of sense resistor (low-side). |
