# TMI6241

**TMI** · Power Distribution Switches · SOT-23-5

TMI6241 from TMI, in a SOT-23-5. 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 | VIN | power_in | Power supply pin; recommended input range is 2.7V to 6V, with a 20V maximum input voltage stress. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Active-high enable: drive to logic-high to enable the IC (EN rising threshold 0.8V to 1.2V, 1.0V typical) and to logic-low to disable it into micro-power shutdown; do not float this pin. |
| 4 | SS | passive | Soft-start program pin: connect a capacitor to ground to set soft-start time, with floating giving the default minimum soft-start time; SS pin voltage is rated -0.3V to 6.0V. |
| 5 | VOUT | power_out | Switch output pin; VOUT and EN voltages are rated -0.3V to 20V absolute maximum. |

## CAD (KiCad official)

- Symbol: `TMI6241`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `tmi6241-etched.step` / `tmi6241-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tmi6241.step` / `tmi6241.glb` are the bare package body.
