APX811-31UG-7

Diodes Incorporated · Supervisor and Reset ICs · SOT-143

APX811-31UG-7 from Diodes Incorporated, 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 reference for the device.
2 RESET output Push-pull reset output. Active-low on the APX811: driven low while VCC is below the reset threshold (3.08V typ. for the -31 option) or while MR is held low, and for approximately 200ms after VCC returns above threshold. Guaranteed valid for VCC > 1V; for valid operation down to VCC = 0V, add a ~100k pull-down.
3 MR input Manual reset input, active low. Driving MR low forces RESET active; must be held low at least 100ns (tW) to be recognized. Typically driven by a push-button to GND with a pull-up to VCC.
4 VCC power_in Operating voltage input, monitored supply. Recommended range 1.1V to 5.5V; absolute maximum -0.3V to +7V. Typical supply current is 30uA at VCC = Vth + 0.2V.
