Activates the power switch when connected to GND (pin1 grounded). On-state input current I_IN(on) ≈ 0.3 mA typ (1 mA max). Input resistance R_I ≈ 1 kΩ (0.5-2.5 kΩ). Max input current ±15 mA. ESD ±1 kV. |+| 2 | Vbb | power_in | Positive power supply voltage. Operating range V_bb(on) 4.9-60 V (typical automotive 12/24/42 V DC). Overvoltage protection V_bbin(AZ) 62 V. Internally tied to pin 4. |+| 3 | OUT | output | High-side switched output to the load. On-state resistance R_ON ≈ 1 Ω typ (1.5 Ω max @ 25 °C). Supports resistive, inductive and capacitive loads with output clamp V_ON(CL) ≥ 60 V during inductive switch-off. |+| 4 | Vbb | power_in | Positive power supply voltage (second Vbb pin, internally tied to pin 2 for improved current handling / thermal spreading via the SOT-223 tab). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Infineon |+| Package | SOT-223 |+| Category | PMIC |+| Pins | 4 |++## CAD (KiCad official)++- Symbol: `BTS4140N`+- Footprint: `Package_TO_SOT_SMD:SOT-223-3_TabPin2`+- 3D model: SOT-223 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Infineon datasheet](docs/bts4140n-datasheet.pdf) (20 pp, sha256 `e66c2404cd7d0caa`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
