APX803S-29SR-7

Diodes Incorporated · Supervisor and Reset ICs · SOT-23

APX803S-29SR-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 VTH (2.93V typ for -29) and remains low for tDELAY (240ms typ) after VCC returns above threshold. Requires an external pull-up resistor. Sinks up to ~3.5mA at VOL = 0.4V; guaranteed valid logic low for VCC > 1V.
2 GND power_in Device ground reference.
3 VCC power_in Operating voltage input and monitored supply. Recommended operating range 1.0V to 5.5V (absolute max 6.0V). The reset threshold is sensed on this pin; internal supply current is ~10µA typical (15µA max) above threshold.
