# MAX6383XR31D3+T

**Maxim Integrated** · Monitors & Reset Circuits · SC-70-3

MAX6383XR31D3+T from Maxim Integrated, in a SC-70-3. 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. |
| 2 | RESET | output | Active-low open-drain reset output that goes low when VCC drops below the reset threshold and stays low for the reset timeout period after VCC exceeds it, requiring an external pullup resistor. |
| 3 | VCC | power_in | Supply voltage for the device and input for the fixed VCC reset threshold monitor, with an operating range of 1.0V to 5.5V. |
