INA190A2IDDFR from Texas Instruments, in a TSOT-23-8. 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 | VS | power_in | Analog power supply voltage, 1.7 V to 5.5 V. |
| 2 | ENABLE | input | Digital input enable pin; when driven to VS device is enabled for current sensing, when driven to GND device is disabled with output in high-impedance state. |
| 3 | REF | input | Analog input reference voltage enabling bidirectional current sensing with externally applied voltage. |
| 4 | GND | power_in | Analog ground. |
| 5 | OUT | output | Analog output providing amplified difference voltage from IN+ to IN- pins, offset by REF pin voltage. |
| 6 | NC | unconnected | Not internally connected; may be left floating or connected to any voltage between GND and VS. |
| 7 | IN+ | input | Current-sense amplifier positive input; connect to bus voltage side of sense resistor for high-side sensing or load side for low-side sensing. |
| 8 | IN- | input | Current-sense amplifier negative input; connect to load side of sense resistor for high-side sensing or ground side for low-side sensing. |
