APX803S-31SR-7

Diodes Incorporated · Supervisor and Reset ICs · SOT-23

APX803S-31SR-7 from Diodes Incorporated, in a SOT-23. 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 RESET output Active-low, open-drain reset output. Asserts low when VCC falls below the reset threshold (3.08V typ. for -31) and remains low for the reset timeout (240ms typ.) after VCC returns above the threshold. Rated to sink up to 20mA; guaranteed valid low for VCC > 1V. Requires an external pull-up resistor to the desired logic rail.
2 GND power_in Device ground reference.
3 VCC power_in Operating supply voltage input and monitored rail. Recommended operating range 1.0V to 5.5V; absolute max 6.0V. Typical supply current 10µA. Reset is asserted whenever VCC falls below the preset threshold (3.08V typ. for the -31 option).
