# INA301A1QDGKTQ1

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

INA301A1QDGKTQ1 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 input, operating range 2.7 V to 5.5 V (absolute maximum supply 6 V). |
| 2 | OUT | output | Analog output that provides the output voltage, limited to GND - 0.3 V to (VS) + 0.3 V. |
| 3 | LIMIT | input | Analog alert threshold limit input used to set the overcurrent alert threshold with a single external resistor, limited to GND - 0.3 V to (VS) + 0.3 V. |
| 4 | GND | power_in | Analog ground reference for the device. |
| 5 | RESET | input | Digital input that selects transparent mode when pulled low and latch mode when pulled high, limited to GND - 0.3 V to (VS) + 0.3 V; the latch is cleared by pulling low for at least 100 ns. |
| 6 | ALERT | output | Active-low, open-drain overlimit alert output, limited to GND - 0.3 V to 6 V. |
| 7 | IN- | input | Negative differential voltage input, common-mode limited to GND - 0.3 V to 40 V; connect to the load side of the shunt resistor. |
| 8 | IN+ | input | Positive differential voltage input, common-mode limited to GND - 0.3 V to 40 V; connect to the supply side of the shunt resistor. |
