AX6901FRA from Axelite Tech, 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 pin for the AX6901/2 pinout. |
| 2 | RESET | output | Active-low push-pull reset output for AX6901, asserted when VCC falls below the threshold and held for at least 200ms (typ.) after VCC rises above it, with output state guaranteed down to VCC = 1.0V. |
| 3 | VCC | power_in | Operating voltage input, range 1.0V to 6V with absolute maximum of GND + 6.5V. |
