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 | OUT | power_out | Power output to the load. Pins 1 and 5 must be externally shorted; not shorting both outputs increases R_ON, reduces peak current capability, and degrades current-sense accuracy. |+| 2 | IN | input | Control input; activates the power switch when pulled low (shorted to ground via R_IN). Required current capability of input switch typ. 1.6 mA (max 2.4 mA); turn-off current max 30 µA. Under-voltage shutdown at V_bIN ≈ 2.5-3.5 V. |+| 3 | Vbb | power_in | Positive supply voltage. Operating range 5.5-62 V; absolute max 62 V (48 V for full short-circuit protection); load-dump 70 V. Tab and pin 3 are internally shorted. Integrated series resistor R_bb ≈ 100 Ω in the V_bb line. |+| Tab | Vbb | power_in | Exposed thermal tab, internally shorted to pin 3 (Vbb). Provides the primary thermal path; must be soldered to Vbb copper for the specified R_thJA (45-55 K/W on 50×50 mm 1.5 mm FR4 with 6 cm² copper). |+| 4 | IS | output | Sense/diagnostic output. In normal operation delivers a current proportional to the load current with ratio k_ILIS ≈ 9000 (I_S = I_L / k_ILIS). In fault conditions (overload, overtemperature, short circuit) sources a defined fault current I_IS,fault ≈ 4.0-7.5 mA. Requires external R_IS (typ. 1 kΩ) to signal GND; leave open if unused. |+| 5 | OUT | power_out | Power output to the load. Pins 1 and 5 must be externally shorted; not shorting both outputs increases R_ON, reduces peak current capability, and degrades current-sense accuracy. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Infineon |+| Package | TO-252-4 |+| Category | PMIC |+| Pins | 6 |++## CAD (KiCad official)++- Symbol: `BTS6163D`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252-4 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Infineon datasheet](docs/bts6163d-datasheet.pdf) (18 pp, sha256 `bfbbb17d73f04bc9`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
