STEF05DPUR from STMicroelectronics, in a UDFN-10-EP(3x3). 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 | VOUT/Source | output | Output source pin connected to the MOSFET source and fuse output terminal. |
| 2 | VOUT/Source | output | Output source pin connected to the MOSFET source and fuse output terminal. |
| 3 | VOUT/Source | output | Output source pin connected to the MOSFET source and fuse output terminal. |
| 4 | VOUT/Source | output | Output source pin connected to the MOSFET source and fuse output terminal. |
| 5 | VOUT/Source | output | Output source pin connected to the MOSFET source and fuse output terminal. |
| 6 | NC | unconnected | No connection; pin not used. |
| 7 | I-Limit | passive | External resistor connection to set overload and short-circuit current limit levels. |
| 8 | En/Fault | tri_state | Tri-state, bi-directional interface for output control and thermal fault signaling via intermediate voltage state. |
| 9 | dv/dt | passive | External capacitor connection for controlling output voltage ramp time; leave open for typical 1 ms ramp. |
| 10 | GND | power_in | Ground reference pin. |
| 11 | VCC | power_in | Positive supply input voltage pin with exposed thermal pad. |
