INA310B3QDGKRQ1 from Texas Instruments, in a VSSOP-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 | VS | power_in | Power supply input, specified for 2.7 V to 20 V operation. |
| 2 | OUT | output | Output voltage of the current sense amplifier. |
| 3 | CMPIN | input | Comparator input; the absolute maximum range is GND - 0.3 V to the lesser of 5.5 V or VS. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | RESET | input | Active-low comparator reset pin: Low selects transparent mode and High selects latch mode. |
| 6 | CMPOUT | output | Open-drain comparator output that latches high when RESET is High; its absolute maximum is GND - 0.3 V to 22 V. |
| 7 | IN- | input | Shunt resistor negative sense input; connect to the load side of the sense resistor for high-side use and to the ground side for low-side use. |
| 8 | IN+ | input | Shunt resistor positive sense input; connect to the bus-voltage side of the sense resistor for high-side use and to the load side for low-side use. |
