MAX811T

TECH PUBLIC · Supervisor And Reset ICs · SOT-143

MAX811T from TECH PUBLIC, in a SOT-143. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground; return path for all supply current; connect to system ground.
2 /RESET output Active-low reset output; asserts low when VCC falls below the reset threshold (3.01 V for the T suffix); deasserts 140 ms after VCC rises back above the threshold.
3 MR input Active-low manual reset input with internal 20 kΩ pull-up resistor; holding MR low asserts the reset output; may be left floating, driven by TTL/CMOS logic, or shorted to GND via a switch.
4 VCC power_in Supply voltage input and the monitored rail; operating range 1.0 V to 5.5 V; reset asserts when VCC falls below 3.01 V (T suffix).

  • Symbol: MAX811T
  • Footprint: Package_TO_SOT_SMD:SOT-143
  • 3D model: SOT-143 (KiCad packages3D, STEP)
  • 3D model files: max811t-etched.step / max811t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); max811t.step / max811t.glb are the bare package body.
