APX803L40-41SA-7

Diodes Incorporated · Supervisor And Reset ICs · SOT-23-3

APX803L40-41SA-7 from Diodes Incorporated, in a SOT-23-3. 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 Ground reference (0V). Connect to system ground.
2 RESET output Active-low, open-drain reset output. Asserts low when VCC falls below the internal threshold (4.1V for the -41 option) and remains asserted for the tDELAY timeout (typ. 450ms for the L40 variant) after VCC recovers above the release threshold. Requires an external pull-up resistor (typical 100kΩ). VOL ≤ 0.4V at ISINK = 3.5mA; maximum pin voltage 6.0V.
3 VCC power_in Operating voltage input and monitored supply rail. Recommended operating range 0.9V to 5.5V; absolute maximum 6.0V. Typical bypass 100nF ceramic (CIN) to GND. Supply current ≈ 1µA typ, 2.5µA max.
