BTS723GW from Infineon, in a SOIC-14. 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 | Vbb | power_in | Positive power supply voltage (Vbb), operating range 7.0 to 58 V. Multiple Vbb pins (1, 7, 8, 14) share the leadframe; wire for max simultaneous short-circuit currents from both channels and low thermal resistance. |
| 2 | IN1 | input | Input for channel 1: activates channel 1 on logic-high signal. CMOS-compatible, ground-referenced with integrated 20 kΩ input series resistor. Absolute max input voltage ±42 V DC; max input current ±2.0 mA DC. |
| 3 | ST1 | output | Diagnostic feedback for channel 1: open-drain status output. Integrated pull-up via SPU pin; reports open-load (OFF state) and thermal shutdown (ON state). Max status current ±2.0 mA DC. |
| 4 | GND | power_in | Logic ground. Independent from load ground. External current-limit resistor (150 Ω recommended) advised for Vbb > Vbb(AZ). |
| 5 | ST2 | output | Diagnostic feedback for channel 2: open-drain status output. Integrated pull-up via SPU pin; reports open-load (OFF state) and thermal shutdown (ON state). Max status current ±2.0 mA DC. |
| 6 | IN2 | input | Input for channel 2: activates channel 2 on logic-high signal. CMOS-compatible, ground-referenced with integrated 20 kΩ input series resistor. Absolute max input voltage ±42 V DC; max input current ±2.0 mA DC. |
| 7 | Vbb | power_in | Positive power supply voltage (Vbb), operating range 7.0 to 58 V. Shares leadframe with pins 1, 8, 14. |
| 8 | Vbb | power_in | Positive power supply voltage (Vbb), operating range 7.0 to 58 V. Shares leadframe with pins 1, 7, 14. |
| 9 | OUT2 | power_out | Protected high-side power output of channel 2. On-state resistance ~90 mΩ typ (each channel, Tj=25°C); nominal load current 2.9 A (one channel active); current limitation 8 A. Pins 9 and 10 must be connected in parallel for spec operation. |
| 10 | OUT2 | power_out | Protected high-side power output of channel 2 (parallel with pin 9). Must be tied to pin 9. |
| 11 | SPU | input | Status Pull-Up: connection for external pull-up voltage source (max ±42 V DC) for the open-drain ST1/ST2 status outputs. Pull-up resistors (~12 kΩ / 850 Ω network) are integrated internally. |
| 12 | OUT1 | power_out | Protected high-side power output of channel 1. On-state resistance ~90 mΩ typ (each channel, Tj=25°C); nominal load current 2.9 A (one channel active); current limitation 8 A. Pins 12 and 13 must be connected in parallel for spec operation. |
| 13 | OUT1 | power_out | Protected high-side power output of channel 1 (parallel with pin 12). Must be tied to pin 12. |
| 14 | Vbb | power_in | Positive power supply voltage (Vbb), operating range 7.0 to 58 V. Shares leadframe with pins 1, 7, 8. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 541 faces against 237 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.
