MAX809REUR+T

Analog Devices Inc Maxim Integrated · Supervisor And Reset ICs · SOT-23-3

MAX809REUR+T from Analog Devices Inc 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 reference for the supervisor, with all voltage levels specified relative to GND.
2 RESET output Push-pull active-low reset output that remains low while VCC is below the reset threshold and for at least 140ms after VCC rises above the reset threshold; the output is guaranteed valid down to VCC = 1V.
3 VCC power_in Supply voltage input (+5V, +3.3V, +3.0V, or +2.5V systems), with VCC range of 1.2V to 5.5V over TA = -40°C to +105°C for the EUR (SOT23) versions.
