INA303A1IPWR from Texas Instruments, in a TSSOP-14. 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 | Analog power supply, 2.7 V to 5.5 V |
| 2 | OUT | output | Output voltage |
| 3 | LIMIT1 | input | ALERT1 threshold limit input; see the Setting Alert Thresholds section for details on setting the limit threshold |
| 4 | REF | input | Reference voltage, 0 V to VS |
| 5 | GND | power_in | Analog ground |
| 6 | LATCH1 | input | Transparent or latch mode selection input |
| 7 | LATCH2 | input | Transparent or latch mode selection input |
| 8 | NC | unconnected | No internal connection |
| 9 | LIMIT2 | input | ALERT2 threshold limit input; see the Setting Alert Thresholds section for details on setting the limit threshold |
| 10 | DELAY | input | Delay timing input; see the Alert Outputs section for details on setting the delayed alert response for comparator 2 |
| 11 | ALERT2 | tri_state | Open-drain output; active-low; underlimit alert for the INA303 |
| 12 | ALERT1 | tri_state | Open-drain output, active-low overlimit alert |
| 13 | IN- | input | Connect to load side of the current-sensing resistor |
| 14 | IN+ | input | Connect to supply side of the current-sensing resistor |
