**Analog Devices** · Monitors & Reset Circuits · SOT-143-4

ADM6315-29D3ARTZR7 from Analog Devices, 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 | Ground reference for all signals, 0 V. |
| 2 | RESET | output | Active-low open-drain reset output that remains low while VCC is below the reset threshold or MR is low, and for a minimum of 140 ms (D3 option) after VCC rises above the threshold and MR is high. |
| 3 | MR | input | Active-low debounced manual reset input that ignores pulses of 100 ns (typical), is guaranteed to accept pulses greater than 1 μs, and is left floating when not used. |
| 4 | VCC | power_in | Monitored supply voltage, operating range 1 V to 5.5 V (absolute maximum −0.3 V to +6 V). |
