TECH PUBLIC · Supervisor And Reset ICs · SOT-143
TPAX811TS4 from TECH PUBLIC, in a SOT-143. 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. |
| 2 | ~{RESET} | output | Active-low push-pull reset output that goes low when VCC falls below the reset threshold and stays low for at least 140 ms after VCC rises above the threshold. |
| 3 | ~{MR} | input | Manual reset input, active low, with internal 20kΩ pull-up; reset stays asserted while MR is low and for 140 ms after MR returns high; leave floating if unused, drive with TTL/CMOS logic or short to ground with a switch. |
| 4 | VCC | power_in | Positive supply input, both the operating supply of the internal circuit and the monitored voltage; recommended range 1.0 to 5.5 V, absolute maximum -0.3 to 6 V. |
