Analog Devices Inc Maxim Integrated · Supervisor And Reset ICs · SOT-23
MAX809LEUR+T from Analog Devices Inc Maxim Integrated, 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 for the supervisor, as listed in the pin description table. |
| 2 | RESET | output | Active-low push-pull reset output for the MAX809 that remains low while VCC is below the reset threshold and for at least 140ms after VCC rises above the reset threshold. |
| 3 | VCC | power_in | Supply voltage monitored by the supervisor (+5V, +3.3V, +3.0V, or +2.5V); the MAX8__EUR is specified for VCC of 1.2V to 5.5V over TA = -40°C to +105°C. |
