APX811-40UG-7

Diodes Incorporated · Supervisor and Reset ICs · SOT-143

APX811-40UG-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 Device ground reference.
2 RESET output Push-pull reset output. Active-low on APX811: driven low while VCC is below the reset threshold (4.00V nominal for the -40 variant) or MR is low, and remains asserted for at least 240ms (200ms typical) after VCC returns above the threshold. VOL <= 0.4V at 3.2mA sink; VOH >= 0.8*VCC at 500uA source.
3 MR input Manual reset input, active low. Driving MR low forces RESET to become active; minimum pulse width tW = 100ns. Typically tied to a pushbutton to GND with an internal or external pull-up.
4 VCC power_in Supply voltage input, 1.1V to 5.5V recommended operating range (absolute max 7V). Monitored against the internal reset threshold (4.00V nominal for the -40 option). Typical supply current 30uA.
