# STMPS2252TTR

**STMicroelectronics** · Power Distribution Switches · MSOP-8-EP

STMPS2252TTR from STMicroelectronics, in a MSOP-8-EP. 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 reference pin for the device. |
| 2 | IN | power_in | VCC input for the device, specified at 2.7 V to 5.5 V. |
| 3 | EN1 | input | Channel 1 enable, active high on the STMPS2252 (active low on the STMPS2242 and STMPS2262). |
| 4 | EN2 | input | Channel 2 enable, active high on the STMPS2252 (active low on the STMPS2242 and STMPS2262). |
| 5 | OC2 | output | Open-drain fault indication output for channel 2, with output low voltage of 0.4 V maximum at 5 mA. |
| 6 | OUT2 | power_out | Output of channel 2, the high-side MOSFET switch output limited to 500 mA continuous for the STMPS2252. |
| 7 | OUT1 | power_out | Output of channel 1, the high-side MOSFET switch output limited to 500 mA continuous for the STMPS2252. |
| 8 | OC1 | output | Open-drain fault indication output for channel 1, with output low voltage of 0.4 V maximum at 5 mA. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `STMPS2252TTR`
- Footprint: `Package_SO:MSOP-8-1EP_3x3mm_P0.65mm_EP1.5x1.8mm`
- 3D model: MSOP-8-EP (KiCad packages3D, STEP)
- 3D model files: `stmps2252ttr-etched.step` / `stmps2252ttr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `stmps2252ttr.step` / `stmps2252ttr.glb` are the bare package body.
