**Texas Instruments** · Current Sense Amplifiers · VSSOP-8

INA301A1IDGKT 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 | Analog power supply, 2.7 V to 5.5 V. |
| 2 | OUT | output | Analog output that provides the output voltage. |
| 3 | LIMIT | input | Alert threshold limit input that sets the current-limit threshold; see the Setting The Current-Limit Threshold section for details. |
| 4 | GND | power_in | Analog ground. |
| 5 | RESET | input | Digital input that selects transparent or latch mode. |
| 6 | ALERT | output | Overlimit alert output that is active-low and open-drain. |
| 7 | IN- | input | Analog input to be connected to the load side of the shunt resistor. |
| 8 | IN+ | input | Analog input to be connected to the supply side of the shunt resistor. |
