BTS441RG from Infineon, in a TO-263-4. 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 | GND | power_in | Ground pin of the logic and protection circuitry, with operating current IGND of 2 mA typ (4 mA max) at VIN = 5 V, and a 150 Ω external resistor required in the GND connection for reverse battery protection. |
| 2 | IN | input | Ground-referenced CMOS-compatible input with 3.8 kΩ typ input resistance, turn-on threshold 1.2 to 2.2 V, turn-off threshold min 0.8 V, and DC input voltage range -10 to +16 V. |
| 3 | VBB | power_in | Positive supply pin with operating voltage 4.75 V to 41 V (Vbb(on)), 43 V max supply rating, and on-state resistance to OUT of 20 mΩ max at 25 °C. |
| 4 | ST | output | Open-drain diagnostic status output that reports open load in the OFF state and overtemperature, with a low voltage of max 0.4 V at IST = 1.6 mA and a DC current rating of ±5.0 mA. |
| 5 | OUT | power_out | Protected high-side power output to the load, with nominal load current 21 A, current limit 65 A typ, and inductive-load clamp VON(CL) of 43 to 52 V at 25 to 150 °C. |
