STMPS2252MTR from STMicroelectronics, in a SO-8. 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 connection providing 0 V reference for all circuits. |
| 2 | IN | power_in | Supply voltage input accepting 2.7 to 5.5 V to power the device and the output switches. |
| 3 | EN1 | input | Active-high enable input for channel 1; apply ≥2.0 V to turn ON the power switch with maximum 5 ms turn-on time, ≤0.8 V to turn OFF. |
| 4 | EN2 | input | Active-high enable input for channel 2; apply ≥2.0 V to turn ON the power switch with maximum 5 ms turn-on time, ≤0.8 V to turn OFF. |
| 5 | OC2 | tri_state | Open-drain fault output for channel 2; asserts low (≤0.4 V) when overcurrent or thermal shutdown is detected, after 4-15 ms fault blanking delay. |
| 6 | OUT2 | power_out | High-side power output of channel 2; delivers up to 500 mA continuous current with on-state resistance of 105-115 mΩ at VI = 5.0 V. |
| 7 | OUT1 | power_out | High-side power output of channel 1; delivers up to 500 mA continuous current with on-state resistance of 105-115 mΩ at VI = 5.0 V. |
| 8 | OC1 | tri_state | Open-drain fault output for channel 1; asserts low (≤0.4 V) when overcurrent or thermal shutdown is detected, after 4-15 ms fault blanking delay. |
