SR2HARU from STMicroelectronics, in a UDFN-6(1.3x1.6). 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 | VSS | power_in | Ground pin for the device, providing return path for supply current. |
| 2 | SR1 | input | Secondary push-button Smart Reset input, active low, with optional pull-up resistor; requires simultaneous assertion with SR0 for at least tSRC to trigger reset output. |
| 3 | RST | output | Reset output, active low, open drain type, maximum output voltage low 0.3 V when sinking 3.2 mA at VCC = 4.5 V. |
| 4 | NC | unconnected | Not connected pin (not bonded); should be connected to VSS. |
| 5 | SR0 | input | Primary push-button Smart Reset input, active low, with optional pull-up resistor; requires simultaneous assertion with SR1 for at least tSRC to trigger reset output; test mode triggered by overvoltage above VCC + 0.9 V. |
| 6 | VCC | power_in | Positive supply voltage for the device, operating range 1.65 V to 5.5 V; recommend 0.1 µF decoupling capacitor to VSS. |

Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
