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 | BS | passive | Bootstrap pin. A capacitor (typ. 0.1µF) connected between LX and BS forms a floating supply for the high-side switch driver. Absolute max: -0.3V to 23V. |+| 2 | GND | power_in | Ground pin. Return for all internal circuitry and the low-side power MOSFET source. |+| 3 | FB | input | Output voltage feedback input. Connect to the center point of the external resistor divider from VOUT to GND. Regulated to internal VREF = 0.6V (typ., 0.588V-0.612V). Absolute max: -0.3V to 6V. |+| 4 | EN | input | Enable input. Drive logic-high (≥1.5V) to enable the IC; drive logic-low (≤0.3V) to disable and enter micro-power shutdown (~5µA). Do not leave floating. Shares absolute max with input supply (-0.3V to 20V). |+| 5 | IN | power_in | Power supply input. Operating range 4.5V to 18V; OVP threshold typ. 19.3V. Bypass to GND with a low-ESR ceramic capacitor close to the pin. |+| 6 | LX | output | Switching node. Connection to the drains of the internal high-side and low-side power MOSFETs; drives the external inductor. Absolute max: -0.3V to 20V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TMI |+| Package | TSOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## CAD (KiCad official)++- Symbol: `TMI3253SH`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: TSOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [TMI datasheet](docs/tmi3253sh-datasheet.pdf) (14 pp, sha256 `91d79790ad36d892`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
