# MAX6328UR30+T

**Maxim Integrated** · Monitors & Reset Circuits · SOT-23-3

MAX6328UR30+T from Maxim Integrated, in a SOT-23-3. 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 on the MAX6328; remains low while VCC is below the reset threshold and for at least 100ms after VCC rises above it, and needs an external pull-up (absolute max -0.3V to +6V). |
| 3 | VCC | power_in | Supply voltage, 1.0V to 5.5V (TA = 0°C to +70°C) or 1.2V to 5.5V (TA = -40°C to +85°C); absolute maximum -0.3V to +6V. |
