APX803L20-29SR-7

Diodes Incorporated · Supervisor and Reset ICs · SOT-23R

APX803L20-29SR-7 from Diodes Incorporated, in a SOT-23R. 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 Reset output pin. Open-drain, active-low. Asserted (pulled low) when VCC is below the 2.9V threshold and for the 220ms tDELAY timeout after VCC recovers. Requires an external pull-up (typ. 100k) to VCC. VOL = 0.4V max at ISINK = 3.5mA; max rating 5.5V.
2 GND power_in Device ground reference.
3 VCC power_in Operating supply voltage input and monitored rail. Recommended operating range 0.9V to 5.5V; absolute max 6.0V. Also serves as the sensed supply for reset detection at the internal 2.9V threshold.
