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 | Connect to the supply side of the shunt resistor; the common-mode input range is -0.2 V to +26 V and the pins withstand 26 V even with VS removed. |+| 2 | VS+ | power_in | Power supply pin with an operating range of 2.7 V to 5.5 V, bypassed with a 0.1 µF capacitor placed as close to the pin as possible. |+| 3 | ALERT | output | Active-low, open-drain over-limit alert output that should use a 10 kΩ pull-up and must not be pulled up above 5.5 V. |+| 4 | RESET | input | Digital input that selects the alert mode, with low for transparent mode and high for latch mode, and an absolute maximum range of GND - 0.3 V to VS + 0.3 V. |+| 5 | GND | power_in | Device ground that should be connected, together with the thermal pad, to a solid ground plane on the PCB. |+| 6 | NC | unconnected | Internal connection that may be left floating, connected to ground, or connected to the supply. |+| 7 | CMPREF | input | Comparator reference input that sets the alert threshold through a resistor divider or an external reference, with an absolute maximum range of GND - 0.3 V to VS + 0.3 V. |+| 8 | CMPIN | input | Comparator input signal that connects directly to VOUT when no extra hysteresis is needed, or through an external RHYS resistor to add hysteresis, with an absolute maximum range of GND - 0.3 V to VS + 0.3 V. |+| 9 | VOUT | output | Current-sense amplifier output equal to the differential input voltage times the gain of 20, 50, 100, or 200 V/V, with an absolute maximum range of GND - 0.3 V to VS + 0.3 V. |+| 10 | IN- | input | Connect to the load side of the shunt resistor; the common-mode input range is -0.2 V to +26 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VSSOP-10-0.5mm |+| Category | Amplifiers/Comparators |+| Pins | 10 |++## CAD (KiCad official)++- Symbol: `INA381A1QDGSRQ1`+- Footprint: `Package_SO:MSOP-10_3x3mm_P0.5mm`+- 3D model: VSSOP-10-0.5mm (KiCad packages3D, STEP)+- 3D model files: `ina381a1qdgsrq1-etched.step` / `ina381a1qdgsrq1-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ina381a1qdgsrq1.step` / `ina381a1qdgsrq1.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/ina381-q1) (38 pp, sha256 `9960fd85de1ad05d`, retrieved 2026-10-07, tier: lcsc)+- **Datasheet language:** Chinese.
