VN7050ASTR from STMicroelectronics, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | INPUT | input | Voltage-controlled logic input pin with hysteresis, compatible with 3 V and 5 V CMOS outputs. Controls the high-side output switch state (VIL ≤ 0.9 V, VIH ≥ 2.1 V, hysteresis 0.2 V). Recommend 15 kΩ pull-down to GND when unused. |
| 2 | SEn | input | Sense enable pin, active-high, 3 V/5 V CMOS-compatible. Enables the MultiSense diagnostic analog output; when low, MultiSense is disabled which allows OFF-state diagnosis inhibit and sense-resistor sharing between similar devices. |
| 3 | GND | power_in | Device ground. Must be reverse-battery protected by an external diode/resistor network (see Table 1). DC reverse ground pin current limited to 200 mA absolute max. |
| 4 | MultiSense | output | Multiplexed analog sense output pin. Sources a current proportional to the selected diagnostic (load current, VCC supply voltage, or chip temperature) into an external RSENSE to produce a voltage. Requires 1 kΩ pull-down if grounded when unused; must not be tied directly to ground. |
| 5 | VCC | power_in | Battery supply connection. Operating range 4 V to 28 V (40 V transient clamp). Pin 5 and pin 8 are both VCC and must be tied together on the board. |
| 6 | OUTPUT | output | Protected high-side power output to load. Internally current-limited (typ 30 A DC short-circuit current, RON typ 50 mΩ). Pin 6 and pin 7 are internally the same OUTPUT node and must be tied together on the board. |
| 7 | OUTPUT | output | Protected high-side power output to load (paralleled with pin 6). Tie externally to pin 6 for full current-handling capability. |
| 8 | VCC | power_in | Battery supply connection (paralleled with pin 5). Tie externally to pin 5. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 499 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
