HXY MOSFET · Supervisor And Reset ICs · SOT-23
MAX809T-HXY from HXY MOSFET, 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 | Chip ground terminal of the supervisor (datasheet pin table: 芯片接地端). |
| 2 | RESET | output | Reset output; VOL is at most 0.3 V at 1.2 mA sink when VCC is at Vthmin, and VOH is at least 0.8×VCC at 500 µA source when VCC is above Vthmax. |
| 3 | VCC | power_in | Supply/monitored voltage input; operating range is 1.0 V to 6.0 V, with a 6.5 V absolute maximum input voltage. |
