INA250A1QPWRQ1 from Texas Instruments, in a TSSOP-16. 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 | Analog input that connects to the load side of the current path; datasheet lists IN- pins 1, 2 and 3 together as "Connect to load." |
| 2 | IN- | input | Analog input that connects to the load side of the current path; datasheet lists IN- pins 1, 2 and 3 together as "Connect to load." |
| 3 | IN- | input | Analog input that connects to the load side of the current path; datasheet lists IN- pins 1, 2 and 3 together as "Connect to load." |
| 4 | SH- | output | Kelvin connection to the internal shunt; connect to VIN- if no filtering is needed, and see Figure 7-4 for filter recommendations. |
| 5 | VIN- | power_in | Voltage input from the load side of the shunt resistor. |
| 6 | GND | power_in | Analog ground. |
| 7 | REF | input | Reference voltage input, which must be between 0 V and VS (up to 18 V). |
| 8 | GND | power_in | Analog ground. |
| 9 | OUT | output | Analog output carrying the output voltage. |
| 10 | VS | power_in | Device power supply, 2.7 V to 36 V. |
| 11 | GND | power_in | Analog ground. |
| 12 | VIN+ | power_in | Voltage input from the supply side of the shunt resistor. |
| 13 | SH+ | output | Kelvin connection to the internal shunt; connect to VIN+ if no filtering is needed, and see Figure 7-4 for filter recommendations. |
| 14 | IN+ | input | Analog input that connects to the supply side of the current path; datasheet lists IN+ pins 14, 15 and 16 together as "Connect to supply." |
| 15 | IN+ | input | Analog input that connects to the supply side of the current path; datasheet lists IN+ pins 14, 15 and 16 together as "Connect to supply." |
| 16 | IN+ | input | Analog input that connects to the supply side of the current path; datasheet lists IN+ pins 14, 15 and 16 together as "Connect to supply." |
