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). |
