APX803S05-29SR-7

Diodes Incorporated · Supervisor And Reset ICs · SOT-23

APX803S05-29SR-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 pin. Asserted (low) on power-up and whenever VCC falls below VTH (2.89-2.97V for the -29 option), held low for the reset active timeout period (20-70ms, 50ms typ.) after VCC rises above VTH. Requires an external pull-up resistor; guaranteed valid down to VCC = 1V. VOL <= 0.3V at ISINK = 1.2mA. Absolute max voltage -0.3 to 6V; max output sink current 20mA.
2 GND power_in Ground reference for the device.
3 VCC power_in Operating voltage input; the supply being monitored. Recommended operating range 1.0V to 5.5V; absolute max -0.3 to +6.0V. Typical supply current 10µA (max 15µA) at VTH + 0.2V. Bypass with a 100nF capacitor near the pin per the typical application circuit.
