# AIC809-31GUTR

**AIC(Analog Integrations)** · Monitors & Reset Circuits · SOT-23

AIC809-31GUTR from AIC(Analog Integrations), in a SOT-23. 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 pin for the supervisor. |
| 2 | RESET | output | Active-low push-pull reset output that remains low while VCC is below the reset threshold, and is guaranteed to be a logic low for VTH > VCC > 0.9V. |
| 3 | VCC | power_in | Supply voltage pin for the device. |
