MIC6315-29D3UY-TR from Microchip Tech, in a SOT-143-4. 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 | IC ground. |
| 2 | /RESET | output | Active-low open-drain reset output that goes low if VCC falls below the reset threshold and stays asserted for one reset timeout period after VCC exceeds the threshold; requires a pull-up resistor, limited to 6.0V maximum, and remains valid with VCC as low as 1V. |
| 3 | /MR | input | Manual reset input where a logic LOW forces a reset that stays asserted while held low and for one reset timeout period after going HIGH; can be shorted to ground via a switch or driven by TTL/CMOS logic, has a 10 to 30 kΩ internal pull-up (20 kΩ typ), and should be floated if unused. |
| 4 | VCC | power_in | Power supply input with operating range of 1V to 5.5V and absolute maximum of 6.0V. |
